A right angled triangular prism of refractive index `mu_(1)` is kept floating on a liquid (surface) having refractive index `mu_(2)`. The condition such tat light incident normally passes through base of prism as shown in figure.

A ray of light passing through a prism of refracting angle 60^(@) has to deviate by at least 40^(@) . Then refractive index of prism should be

A ray of light passing through a prism of refraction angle 60^(@) has to deviate by atleast 30^(@) . Then, refractive index of prism should be

A thin prism of angle 15^(@) made of glass of refractive index mu_(1)=1.5 is combined with another prism of glass of refractive index mu_(2)=1.75 . The combination of the prism produces dispersion without deviation. The angle of the second prism should be

A transparent cube of side d, made of a material of refractive index mu_(2) , is immersed in a liquid of refractive index mu_(1)(mu_(1)ltmu_(2)) . . A ray is incident on the face AV at an angle theta (shown in the figure). Total internal refraction takes place at point E on the face BC. Then must satisfy:

A prism of refractive index mu_g deviates the incident ray towards its base. If it is immersed in a transparent liquid of refractive index mu_1 such that mu_1 gt mu_g then prism would

A ray PQ is incident normally on the face AB of a triangular prism of refracting angle of 60^(@) , made of a transparent material of refractive index 2/sqrt(3) , as shown in the figure. Trace the path of the ray as it passes through the prism. Also calculate the angle of emergence and angle of deviation.

The refractive index of a prism is 2. this prism can have a maximum refracting angle of

Shown in the figure is a prism of angle 30^(@) and refractive index mu_(p)=sqrt(3) . Face AC of the prism is covered with a thin film of refractive index mu_(f)=2.2 A monochromatic light of wavelength lambda =550 nm fall on the face AB at an angle of incidence of 60^(@) Calculate angle of emergence
