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).

Is the reflection angle as large as the incident angle?
In diffuse reflection, the reflection angle and the incident angle are the same. Diffuse reflection was a reflection phenomenon caused by the rough surface of the reflective surface. All reflected light followed the relationship of the incident angle being equal to the reflection angle.

Primary school mathematics, right angle, acute angle, obtuse angle
In primary school mathematics, a right angle was 90°, an acute angle was greater than 0° but less than 90°, and an obtuse angle was greater than 90° but less than 180°.

How to calculate the reflection angle and refraction angle
The angle of reflection was equal to the angle of incidence. In junior high school physics, the angle of incidence was usually represented by i, and the angle of reflection was represented by r. Therefore, the angle of reflection could be obtained from the angle of incidence.
The angle of refraction can be calculated using the formula n=c/v=sinA /sinB, n = sini:sinr, where n is the index of refraction, c is the speed of light in vacuum, v is the speed of light in the medium, A is the angle of incidence, and B is the angle of refraction. It can also be calculated according to the formula sin 6i/sin 6t =n21, where the angle of incidence is represented by 6i, the angle of refraction is represented by 6t, and n21 is the relative index of refraction of the second medium to the first medium.
In addition, when light enters water or other media diagonally from the air, the angle of refraction is smaller than the angle of incidence. When the angle of incidence increases, the angle of refraction increases. When light enters air diagonally from water or other media, the angle of refraction is greater than the angle of incidence. When light enters vertically from the air (or other media), the direction of transmission does not change. At this time, the angle of incidence, the angle of reflection, and the angle of refraction are all equal to 0°.

At most, there is a counter-proof that the angle is a right angle
When using reduction to absurdity to prove that "at most one angle is a right angle," one first had to raise the proposition that "at most one angle is a right angle," and then set the anti-proposition that "at most two or three angles are right angles."(Since the original proposition indicated that the number of right angles was at most one, then the contradiction was that the number of right angles was two or three). Next, he deduced according to the rules of reasoning to prove the falsehood of the counter-proposition. Finally, according to the Law of Excluded Middle, since the opposite proposition was false, the original proposition that "at most one angle is a right angle" was true.

The physics principle that the angle of incidence equals the angle of reflection
Starting from the principle that light always travels along the fastest path, Helen discovered that the angle of incidence was equal to the angle of reflection. When light travels to different substances, it will be reflected at the interface. The reflected light, the incident light, and the normal line are on the same plane. The reflected light and the incident light are separated on both sides of the normal line, and the reflection angle is equal to the incident angle. It can be summarized as "three lines are in the same plane, two lines are separated, and two angles are equal." This phenomenon was consistent with the law of reflection. Hiro of Alexandria in the 1st century AD first described the relevant content of the law of reflection. In 1823, fresnel introduced the quantitative law of the law of reflection and the law of refraction (fresnel formula). This law holds true when light is shot from one medium to another, such as light from air into water or glass into air. It is widely used in the field of light to explain the reflection of light and related optical phenomena.

The imprint on the forehead of the novel
In the novel, the mark on the forehead had many meanings and functions. In some novels, the mark on the forehead was a symbol of power. For example, in some fantasy novels, the mark could be activated to find hidden enemies, or the mark itself contained a mysterious power that could prevent evil things from approaching. In some Xianxia novels, the mark on the forehead of a particular race was a symbol of instinctive ability. For example, it was instinctive for the people of the Green Spirit Soul Race to use the green mark on their forehead, but there were also situations where the protagonist did not know how to use the mark on his forehead. In addition, in some original novels related to film and television works (such as the mark on the forehead of the silver-haired male lead may indicate a special identity or ability), the mark on the forehead could also become a unique element in the character's image, increasing the character's recognition and reflecting the uniqueness of the character.
