The angle between the incident and reflected rays of light is 68 °. What are the angle of incidence and the angle of reflection?

Behind the laws of reflection of light from a smooth surface, the angle of incidence and the angle of reflection are equal to each other. The reflection angle is written with the letter α (alpha), the reflection angle is β (beta). The condition leaves α + β = 64 degrees, beyond the condition α = β, therefore
β + β = 64
2β = 64
β = 64: 2
β = 32 degrees.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
