How will the angle between the incident on a flat mirror and the reflected rays change with an increase in the angle of incidence by 10?
The angle of incidence is equal to the angle of reflection. This physical law was formulated specifically for a flat mirror. Therefore, the angle between the incident and reflected rays of light will always be equal to – 180 ° minus twice the angle of the incident ray (do not forget: the angles of incidence and reflection are equal!). 180 ° – 2x (where x is the angle of incidence). Hence the answer: with an increase in the angle of incidence by 10 °, the angle between the rays will decrease by 20 °. 180 ° -2 * (x + 10) ° = 180 ° – 2x – 20 °.
