Question

if the angle between the mirror and the incident ray is 45 degrees, what is the angle of reflection
plz help quickly​

Answer 1

here angle of incident is equal to angle of reflection.

there fore 45 degrees

follow me

Answer 2

Explanation:

according to the law of reflection , angle of incidence with respect to normal is equal to the angle of reflection with respect to normal.

the given angle is with the mirror not with the normal.

therefore the angle of incidence is = 90-45 = 45.

therefore angle of reflection is 45.
