The equation `omega=(mu_v-mu_r)/(mu-1)` was derived for a prism having small refracting angle. Is it also valid for a prism of large refracting angle? Is it also valid for a glass slab or a glass sphere?

Can the dispersive power omega = (mu_v-mu_r)/(mu-1) be negative? What is the sign of omega if a hollow prism is immersed into water?

Find the maximum angle of refraction when a light ray is refracted from glass (mu= 1.50) to air.

A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^(@) .What is the refrective index of the material of the prism? The refracting angle of the prism is 60^(@) . If the prism is placed in water (refractive index 1.33) , predict the new angle of minimum deviation of a parallel beam of light .

The critical angle for a given piece of glass is 45^@ . Calculate the polarising angle for it. Also calculate the angle of refraction when light is incident on this glass at an angle of incident equal to i_P

Light rays travel from vacuum into glass whose refractive index is 1.5 If the angle of incidence is 30^(@) calculate the angle of refraction inside the glass.

What is the Breswster angle for air to glass transition? (Refractive indexof glass=1.5)

The angle of incident at which reflected light is totally polarised for reflection from air to glass (refractive index mu ) is

Derive the equation for angle of deviation produced by a prism and thus obtain the equation for refraction for refactive index of material of the prism.
