A mirror is placed at the centre of a sphere and it is rotating with an angular speed `omega`. Incident light falls on the mirror at the centre of the sphere. Find out the linear speed of the light spot on the sphere?

Text Solution

Verified by Experts

Angular speed of mirror `= omega`
Angular speed of Reflected Ray `= 2omega`
Speed of light spot on the mirror : `2omega(R)`
