Question

Если уменьшить угол падения луча на 20 градусов то на сколько изменится угол между падающим и отраженным лучами

Answer 1

угол падения равен углу отражения. если угол падения уменьшится на 20 градусов, соответственно угол отражения тоже уменьшится на 20 градусов. значит угол между падающим и отраженным лучом уменьшится на 40 градусов

Answer 2

Calculating Change in Angle between Incident and Reflected Rays

If the angle of incidence of a ray of light is decreased by 20 degrees, we can calculate the change in the angle between the incident and reflected rays using the law of reflection.

According to the law of reflection, the angle of incidence is equal to the angle of reflection. Therefore, if the angle of incidence is decreased by 20 degrees, the angle of reflection will also decrease by the same amount.

So, if the original angle of incidence is x degrees, the new angle of incidence will be (x - 20) degrees. Consequently, the change in the angle between the incident and reflected rays will also be 20 degrees.

This conclusion is based on the fundamental principle of the law of reflection, which states that the angle of incidence is equal to the angle of reflection.

Therefore, if the angle of incidence of a ray of light is decreased by 20 degrees, the angle between the incident and reflected rays will also decrease by 20 degrees.
