Question

If the incident ray strikes the pole of a spherical mirror at an angle ${45}^{\circ }$ with principal axis, then what would be the angle of reflected ray with principal axis?

• A. ${45}^{\circ }$
• B. ${90}^{\circ }$
• C. $22{\frac{1}{2}}^{\circ }$
• D. None

Answer 1

The correct option is A ${45}^{\circ }$

The laws of reflection hold good for spherical mirrors.

When a ray strikes the pole, the principal axis becomes the normal at the point of incidence

And the angle of incidence equals the angle of reflection.
