If ray of light falls on a mirror at 30^@ angle the reflected angle becomes_______

In a plane mirror if a ray of light reflects at 35^@ angle then what will be the value of incident angle?

A ray of light is incident on a plane mirror at an angle of incidence of 30^@ . The angle of deviation as a result of reflection will be :

A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is 30^(@) . Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? [sin 48^(@) = 0.75]

A ray of light is incident on a concave mirror along its principal axis.What will be the angle of reflection?

If a ray of light is incident on a reflecting medium at the polarising angle, prove that the reflected and the refracted rays are at 90^(@) to each other.

If the sum of the distances of a point from two perpendicular lines in a plane is 1, then its locus is (a)a square (b) a circle (c) a straight line (d) two intersecting lines

Find the deviation produced by reflection at a plane mirror when the angle between the incident and reflected' rays is 80?
