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.

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.

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°.

arch-enemy India
In different context, India had different enemies:
- In the movie," Old Enemy," the film showed many social conflicts. This was a manifestation of the relationship between old enemies in the movie plot. The movie was about a series of events that happened after Saba, a female university teacher, was raped, killed, and burned, including conflicts between students, the police, the school, and the forces behind the suspect.
- In sports, for example, the Indian female wrestler was expelled from the Paris Olympics for violating the rules, while the opponent country won the gold medal. There was a competitive relationship between the two countries.
- In terms of international relations, India may regard China as a traditional enemy. India is afraid of China's overall strength, especially in terms of economy and military. India and Pakistan are often regarded as enemies by the outside world, but some people think that India and India have a short history of founding, so it is not appropriate to call them enemies. From a historical point of view, iran and India had a long-term love-hate relationship. From the geographical environment, civilization development, expansion direction and other factors, the two sides had constant conflicts in history and could be regarded as old enemies.
