Question

pls give step by step solution​

Answer 1

Answer:

Since we know it from laws of reflection that angle made by incident ray to the normal is equal to angle made by reflected ray to normal

i.e. i=r

##i=25^{0}$$(from question)

So r=25

0

solution

Answer 2

A Ray of light is incident on plane mirror at angle of 30 degree what is the angle of reflection???

=> The angle of reflection is 60 degrees. (Note that the angle of incidence is not 30 degrees; it is 60 degrees since the angle of incidence is measured between the incident ray and the normal.)
