प्रश्न
State the direction of incident ray which after reflection from a spherical mirror gets reflected along its own path. Give a reason.
उत्तर
A ray passing through THE CENTRE OF CURVATURE is incident normally on the spherical mirror, gets reflected back along its own path.
A ray passing through the centre of curvature.
It is because the ray is normal to the spherical mirror,
Hence ∠i=0, i.e., the angle of incidence is 0
Therefore, the angle of reflection ∠r=0.
