If incident ray strikes the mirror at `90^@` , what will be the angle of reflection?

A ray, emerging from a point on the object, passing through the centre of curvature C strikes the mirror normally i.e. at 90^@ . Then, the angle of reflection is equal to

If the angle between incident ray and reflected ray is 120^(@) , what is the angle of incidence ?

In the given figure, two mirrors X and Y are situated at an angle of 60^(@) with each other and a ray of light is incident on mirror X at an angle of 50^(@) . When the ray is reflected by the mirror Y, then what is angle of reflection at this mirror?

When a ray of light is incident normally on a plane mirror then the angle of reflection will be

A ray, emerging from a point on the object, passing through the centre of curvature C strikes the mirror normally i.e. at 90^@ . Then, the angle of incidence is equal to

An incident ray strikes a plane mirror at an angle of 15^@ with the mirror. The angle between the incident ray and reflected ray is
