1. A glass plate of thickness 0.6cm and has a refractive index of 1.55. Calculate the time it will take a ray of light to pass through it.
2. Light beam strike a glass plate at an angle of incident of 60 degree, part of the beam being reflected and part refracted. It is observed that the refracted portions make an angle of 90degree with each other. What is the index of refraction of the glass.
3. The absolute indices of refraction of diamond and crown glass are 5/2 and 3/2 respectively. (a) Compute the refractive index of diamond relative to crown glass (b) compute the critical angle between diamond and crown glass.?
