Imagine that parallel rays are incident on an irregular surface.Are the rays reflected from this surface parallel to each other?

X-ray incident on a material

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

Figure shows a transparent hemisphere of radius 3.0 cm made of a material of refractive index 2.0. (a) A narrow beam of parallel rays is incident on the hemisphere as shown in the figure. Are the rays totally reflected at the plane surface ? (b) Find the image formed by the refraction at the first surface. (c) Find the image formed by the reflection or by the refraction at the plane surface. (d) Trace qualitatively the final rays as they come out of the hemisphere.

Define the following terms a.Incident ray

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

For an angle of incidence theta on an equilateral prism of refractive index sqrt(3) , the ray refracted is parallel to the base inside the prism. The value of theta is

Unpolarized light is incident on a plane sheet of water surface. The angle of incidence for which the reflected and refracted rays are perpendicular to each other is ( mu of water =4/3 )

TRUE or FALSE: Incident ray and refracted rays are parallel to the normal.

Unpolarised light is incident on a plane glass surface. What should be the angle of incidence so that the reflected and refracted rays are perpendicular to each other? (Given n=1.5)
