Question

A ray of light is incident on a plane mirror and the angle of incidence is ${25}^o$. What is the angle of reflection?

• A. $0$
• B. ${50}^o$
• C. ${90}^o$
• D. ${25}^o$

Answer 1

Answer: (D)

${25}^o$

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 $r={25}^0$
