Reflection Test...

A person is standing in front of a plane mirror.If the mirror recedes with velocity v , the relative speed of person and his image per second is-

Two plane mirrors are placed perpendicular to each other. A ray strikes one mirror and, after reflection, falls on the second mirror. The ray, after reflection from the second mirror, will emerge:

A person is in a room whose ceiling and two adjacent walls are mirrors. How many images are formed :

Number of images observable between two parallel mirrors is

An object is placed symmetrically between the two plane mirrors inclined at angle of 30^o. Then the total number of images formed is:

Images of an object that is equidistant from the two plane mirrors whose reflecting surfaces make an angle of 90^∘ with one another lie on a/an

Two plane mirrors are inclined to one another at an angle of 40^∘. A point object is placed in between them. The number of images formed due to reflection at both mirrors is

What should be the angle between two plane mirrors so that whatever be the angle of incidence, the incident ray and the reflected ray from the two mirrors be parallel to each other

A ray gets successively reflection from two mirrors inclined at an angle of 40^o. If the angle of incidence on the first mirror is 30^o then the net deviation of this ray after two reflections :

The focal length of a spherical mirror is ____ its radius of curvature.
