Refractive index of glass is 1.5 find critical angle for glass.

Derive the relation between refractive index of the medium and critical angle.

Green light of wavelegth 5,460 overset @A is incident on an air-glass interface.If the refractive index of glass is 1.5.the wavelength of light in glass would be

The refractive index of glass is 1.5 and that of water is 1.3.If the speed of light in water is 2.25 xx 10^8 m s^(-1) ,what is the speed of light in glass?

A double convex lens has radii 20 cm.The refractive index of glass is 1.5.Compure the focal length of this lens in air and when immersed in carbon disulphide of refractive index = 1.63.

For glass-air interface,the critical angle is C.Will the critical angle for glass-water interface be greater or less than C?

The refractive index of glass is 1.5. What is the speed of light in glass? (Speed of light in vacuum is 3.0 × 10^8 m s )

A convex lens has 12 cm focal length in air. What is its focal length in water? (Refractive index of air-water is (1.33) , refractive index for air-glass = (1.5) .

A convex lens has 20 cm focal length in air.What is its focal length in water? (Refractive index of air-water is 1.33 , refractive index for air¬glass = 1.5).
