If a light ray incidence on a liquid from air at `45^@` and get deviated due to refraction `15^@`. What is the refractive index of the liquid?

A ray of light is incident on the plane face of a liquid at an angle 45^(@) and due to refraction the ray is deviated through an angle 15^(@) . Calculate the refractive index of the liquid.

A tank's depth is 2d and the apparent depth of the liquid in the tank is 60 % its actual depth. What is the refractive index of the liquid with respect to air?

If angle of incidence and angle of refraction be 45^@ and 30^@ respectively. What is refractive index of water is

A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence of 45^(@) . The ray undergoes total internal reflection. If mu is the refractive index of the medium with respect to air, select the possible values (s) of mu from the following

If a ray of light is incident on a plate inside water at an angle of 45^(@) , what is the angle of refraction inside the plate? Given that the absolute refractive indices of the plate and water are 1.88 and 1.33 respectively.

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