Question

What is the relation between image velocity,object velocity and mirror velocity?

Answer 1

$\textbf {\huge{ \red {ANSWER }}}$


Velocity of image = VI Velocityof object = Vo Velocity of mirror = VM I Know the fact that VI=-Vo supposing mirror at rest and VI=2VM 

Answer 2

Suppositions used:

Velocity of image = VI

Velocity of object = Vo

Velocity of mirror = VM

I Know the fact that

VI=-Vo supposing mirror at rest

and

VI=2VM supposing object at rest

Now considering both mirror and object in motion,

VI=2VM - Vo I ended up with this equation but my reference book suggests

VI=2VM + Vo
