Three prisms of crown glass, each have angle of prism 9^(@) and two prisms of flint glass are used to make direct vision spectroscope. What will be the angle of flint glass prisms if mu for flint is 1.69 and mu for crown glass is 1.53 ?
The Brewster angle for the glass air interface is 54.74^(@) if a ray of light going from air to glass strikes at an angle of incidence 45^(@) then the angle of refraction is
A ray of light is travelling from glass to air. ("Refractive index of glass =1.5") . The angle of incidence is 50^(@) . The deviation of the ray is
If a ray passes from air to glass in a spherical glass slab and passes through the centre of the slab without deviation, then the angle of incidence from air to glass at the point on the glass slab is.
A ray of light is travelling from glass to air. The angle of incidence in glass is 35^(@) , and angle of refraction in air 60^(@) . What is the refractive index of glass w.r.t. air ?
A water film is formed on a glass block . A light ray is incident on water film from air at an angle 60^(@) . What is the angle of incidence on the glass block ? (Refractive index of glass = 1.5 , Refractive index of water = 4/3)
A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster's angle phi . If mu represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is
