The angle between the velocity vector of object and image is $\frac{π}{α}$ . Velocity are shown in the figure. Then the value of $α$ is :-

Answer:

2.00

Solution:

Resolve the object velocity along and perpendicular to the mirror axis; the image reverses only the longitudinal component.

From the directions in the figure, the angle between the two velocity vectors is $π /2$ .

So $α = 2$ .

Answer: 2.00
