The angle between the reflection angle and the incident angle increases
According to the law of reflection, the angle of reflection is equal to the angle of incidence. If the angle between the reflection angle and the incident angle increases, let the angle increase be the angle of the reflection angle, then it may be that the normal line is close to or far away from the incident ray, causing the incident angle to increase or decrease by the angle of the reflection angle. Because the reflection angle is equal to the incident angle, the reflection angle will also increase or decrease by the angle of the reflection angle, so that the angle between the reflection ray and the incident ray increases or decreases by the angle of the reflection angle. For example, in the problem of mirror rotation, if the normal line is far away from the incident light, the incident angle increases by angle (a), the reflection angle also increases by angle (a), and the angle between the reflected light and the incident light increases by angle (2a).

What is the angle of the earth?
The angle between the Earth's axis of rotation and the plane of its orbit was about 23.5 degrees, and the angle between the Earth's axis of rotation and the horizontal line was 23.4 degrees.
40 degree angle map
The following is a way to draw a 40-degree angle: first draw a ray, so that the center of the protractor and the end of the ray overlap, and the 0° scale line and the ray overlap; then point a point at the 40° scale line of the protractor; then use the end of the drawn ray as the end point, and draw another ray through the point just drawn; finally, mark the symbol on the angle and write the degree. The method to draw a 40-degree angle in the software was to open the software and draw a straight line as a reference line; click on the angle setting and check the angles of 10, 20, 30, and 40; adjust it to the 40-degree position and enter a length of 100 to draw a 40-degree angle. "40 Sisters" is equally exciting. Everyone is welcome to click and read it!
The angle of view in photography
In photography, the field of view was very important. The size of the field of view was related to factors such as the focal length of the lens. Generally speaking, when other conditions were fixed, the shorter the focal length, the larger the field of view. The longer the focal length, the smaller the field of view. Different lenses had different characteristics and uses. For example, the standard lens had a field of view of about 45 degrees, which was widely used; the telephoto lens had a field of view of 40 degrees, which was suitable for long-distance shooting; the wide-angle lens had a field of view of more than 60 degrees, which had a large observation range, but the close-up image might be distorted; the ultra-wide-angle lens had a field of view of 80 - 110 degrees; and the fisheye lens had a field of view close to or equal to 180 degrees, which was an extreme wide-angle lens. The field of view also determined the field of view of the camera. The larger the field of view, the larger the field of view, and the smaller the optical power. The target would not be included in the lens if it exceeded this angle. For optical equipment such as cameras, because the light-sensitive surface was rectangular, the angle of view was often calculated by the diameter of the object on the diagonal of the rectangular light-sensitive surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Diagonal angle of the cube
The two diagonal lines of the cube are in the same plane. Let the length of the cube be a, and the diagonal line of the cube be (<sqrt{2}a>>), the angle between the face diagonal and the body diagonal.(\alpha = \arctan\sqrt{2}\), get (alpha = 54.7356) degrees, the diagonal of the two bodies meet at a point to form two isosceles-shaped triangle, so the top angle of the isosceles-shaped triangle is the top angle.(The angle of the diagonal line)(<beta>= 180 - 2 <alpha>= 70.5288>) degrees; The angle formed by the diagonal and the bottom of the cube is <A>,<A>=<frac{1}><sqrt{3}>>=<approx0.5774>>,<A>=<arcsin0.5774>=<approx35.27 ^{<circ}>(The final result is kept in two decimals). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on teaching plan of inclination angle and slope of a straight line
The following are some of the main points of teaching reflection on the angle of inclination and slope of a straight line: ** 1. Success ** 1. ** Introduction and transition of knowledge ** - When introducing the concept of inclination angle, it could be introduced by saying," Two points determine a straight line. After removing a point, countless straight lines can be made. The difference between these straight lines is the degree of inclination." This could naturally guide students to think about the concept of inclination angle. - It was reasonable to introduce the concept of straight line slope with the help of the concepts of slope angle, slope and the relationship between them learned in junior high school. It could help students transition from familiar knowledge to new knowledge. - From the idea of " two points determine a straight line, the straight line determines the inclination angle, and if the slope exists, the slope is also determined. Can the slope be calculated by any two points on the straight line?", he introduced the slope calculation formula, and set up exercises to let students discover the relationship on their own, which was helpful for the construction of knowledge. 2. ** Details ** - Pay attention to the connection between old and new knowledge, such as the concept of tilt angle and slope, and the knowledge learned before. - For a straight line with a slope of 90°, there was no such error-prone point. It could be understood by students from the essential point of view of the non-existence of the diagonal value, rather than simply a rule. When the slope exists, the relationship between the positive and negative of the slope and the range of the inclination angle is also analyzed in detail and displayed directly, which can deepen the students 'understanding of the concept. - The exercises were set according to the students 'cognitive rules, from special to ordinary, from shallow to deep. 3. ** Infiltrating the way of thinking ** - In the whole teaching process, through the combination of numbers and shapes, students can better understand the concept of inclination angle, slope and the situation where the slope does not exist when the inclination angle is 90°, so that the abstract concept becomes intuitive and easy to understand. 4. ** Overall control of the classroom ** - Focus on summary, interact with students, pay attention to students 'learning status, and help students consolidate their knowledge. - He was good at using multimedia-assisted teaching, and his teaching posture was natural and generous. His Mandarin was standard, and he could give students a good learning experience. ** 2. Inadequacies ** 1. ** Teaching experience ** - The lack of experience caused him to be too nervous in public classes or the first class, repeating the knowledge points too many times, and the time arrangement was unreasonable. For example, he spent too much time on " the existence of slope and the discussion of the positive and negative slope and the value range of the slope angle." This caused the deduction of the slope formula and the explanation of the examples to be insufficient, and even dragged on the class. Moreover, the content of the course was not finished, and the difficult points could not be highlighted and broken through. 2. ** In terms of students 'main body status ** - When emphasizing the key knowledge, the speed was too fast and the number of repetitions was too many, which did not give the students enough space to think and play. For example, in the discussion of the non-existence of the slope of a straight line with an inclination angle of 90°. - They did not pay enough attention to the individual students and did not take into account the learning needs of different students. 3. ** Introduction to class ** - Inappropriate classroom introductions would affect the teaching effect. For example, if the students simply introduced questions or paid too much attention to Descartes 'introduction method, if they did not combine the actual situation of the students with the overall grasp of the course content, it would make the students feel lost or not interested, and it might also lead to a smooth connection in the teaching process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
