Question

If the angle of incidence on a plane mirror is ${45}^o$. What will be its angle of reflection?

• A. ${35}^o$
• B. ${45}^o$
• C. ${135}^o$
• D. ${145}^o$

Answer 1

The correct option is B ${45}^o$

According to laws of reflection, angle of incidence is equal to angle of reflection. So, the angle of incidence being ${45}^0$, the angle of reflection is also ${45}^0$.
