Prism

Two smooth prisms of similar right-triangular sections are arranged on a smooth horizontal plane as shown in figure. The lower prism has a mass eta times the upper prism. The prisms are held in an initial position as shown and are then released. As the upper prism touches the horizontal plane, the distance moved b y the lower prism is

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 minimum angle of deviation is measured to be 40^@ . What is the refractive index of the prism ? If the prism is placed in water (mu = 1.33) , predict the new angle of minimum deviation of the parallel beam. The refracting angle of prism is 60^@ .

Flint glass prism is joined by a crown glass prism to produce dispersion without deviation. The refractive indices of these for mean rays are 1.602 and 1.500 respectively. Angle of prism of flint prism is 10^(@) , then the angle of prism for crown prism will be
