When all the parallel rays reflected from a smooth surface are parallel in one direction, is known as _____ reflection.

The change in phase if a wave is reflected from a rigid surface is

When a light ray is reflected from a wall, the angle of incidence is not equal to the angle of reflection.

Explain the Reflected ray

When light is reflected from a surface it can be either regular reflection or diffuse reflection. The essential difference between regularly and diffusely reflecting surfaces is that

Two plane mirrors are inclined at 70^@ . A ray incident on one mirror at incidence angle theta after reflection falls on the second mirror and is reflected from there parallel to the first mirror, The value of theta is

Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.

A ray of light moving parallel to the X-axis gets reflected from a parabolic mirror whose equation is (y-2)^2=4(x+1) . After reflection , the ray must pass through the point

A ray of light moving parallel to x-axis gets reflected from a parabolic mirror whose equation is 4( x+ y) - y^(2) = 0 . After reflection the ray pass through the pt(a, b) . Then the value of a + b is

When light is polarised by reflection from a transparent surface. a) reflection and refracted rays are mutually perpendicular b) both reflected and refracted rays are plane polarised c) refraction ray is partially polarised d) the R.I., of transparent surface is equal to tangent of Brewster.s angle

Statement I: A beam of light rays has been reflected from a rough surface. Statement II: Amplitude of incident and reflected rays would be different.
