Condition For No Refraction

Explain how twinkling of stars is an effect of atmospheric conditions on refraction of light.

The figure shows an equi-convex lens. What should be the condition of the refractive indices so that the lens becomes diverging?

The diagram shows an equiconvex lens. What should be the condition on the refractive indices so that the lens becomes diverging?

Figure, shows a concavo-convex lens mu_(2) . What is the condition on the refractive indiecs so the at the lens is diverging?

Find the angle of devaition suffered by the light ray shown in figure for following two conditions. The refractive index for the prism material is mu = 3//2 . (i) When the prism is placed in air 9mu = 1) (ii) When the prism is placed in water (mu = 4//3)

State the conditions of total internal reflection. Refractive indices of the given prism material for Red, Blue and Green colors are respectively 1.39, 1.48 and 1.42 respectively. Trace the path of rays through the prism.

For a given incident ray as shown in Fig., the condition of total internal reflection of ray will be satisfied if the refractive index of the block will be. .
