Answer:
An incident ray makes an angle of 75° with the surface of a plane mirror. What will be the angle of reflection? Solution: The angle made by the normal will be 90-75= 15.

please mark me brainliest
Question :
An incident ray makes an angle of 75 °with the surface of a plane mirror. What will be the angle of reflection?
Concept :
● The angle of incidence is always measured from normal to the plane.
● Angle of incidence = Angle of reflection
Solution :
Incident ray makes an angle of 75° with the surface of plane mirror.
[tex]\tt \implies [/tex] Angle of incidence = 90° – 75
[tex]\tt \implies [/tex] Angle of incidence = 15°
[tex]\tt \implies [/tex] Angle of incidence = Angle of reflection
[tex]\tt \implies [/tex] Angle of reflection = 15°
Angle of reflection = 15°.
