Question

which rays striking a spherical mirror will be reflected along itself?
A. A ray parallel to the axis
B. A ray passing through the vertex
C. A ray passing through the principal focus
D. A ray passing through the center of curvature ​

Answer 1

Answer:

(D) option is correct.

Explanation:

When a ray passes through the centre of curvature , it strikes the spherical mirror perpendicularly due to which it gets reflected along its original path.

Answer 2

D. A ray passing through the centre of curvature ​will reflect along itself.

What is reflection?

• Reflection is particle property of light according to which, when a ray is incident on a polished surface, it reflects back into the same medium.

• According to law of reflection, the angle of reflection is equal to angle of reflection.

What is a centre of curvature?

• Centre of curvature is the centre of the sphere from which the aperture has been cut out.
• So, any line passing through centre of curvature is perpendicular to the aperture, which means that the line through centre of curvature is actually along the normal to the aperture.
• The line passing through centre of curvature makes an angle of 0 degree with the normal and so according to the law of reflection, the angle made by reflected ray will also be 0 degree.
