Light passes through a system of two crossed Nicol prisms between which a quartz plate cut at right angles to its optical axis is placed. Determine the minimum thickness of the plate which allows light of wavelength 436 nm to be complately cut off by the system and transmits half the light of wavelength 497 nm . The specific rotation constant of quartz for these wavelength is equal to 41.5 and 31.1 angualr degress per mm respectively.

(i) Find the speed of light of wavelength lambda =780 nm (in air) in a medium of of refractive index µ=1.55. (ii) What is the wave length of this light in the given medium?

When a metal surface is illuminated by a monochromatic light of wave-length lambda , then the potential difference required to stop the ejection of electrons is 3V . When the same surface is illuminated by the light of wavelength 2lambda , then the potential difference required to stop the ejection of electrons is V . Then for photoelectric effect, the threshold wavelength for the metal surface will be

A quartz plate cut parallel to its optical axis is placed between two corssed Nicol prisms so that principle directions form an angle of 45^(@) with the optical axis of the plate. What is the minimum thickness of that plate transmitting light of wavelength lambda = 643nm with maximum intensity while greatly reducing the intensity of transmitting light of wavelength lambda_(2) = 564 nm ? The difference of refractive indieces indices for extroardianry and ordinary rays is assumed to be equal to n_(e) - n_(0) = 0.0090 for both wavelengths.

The angles of incidence and refraction of a monochromatic ray of light of wavelength lamda at an air-glass interface are i and r, respectively. A parallel beam of light with a small spread delta lamda in wavelength about a mean wavelength lamda is refracted at the same air-glass interface. The refractive index mu of glass depends on the wavelength lamda as mu(lamda) = a + b//lamda2 where a and b are constants. Then the angular spread in the angle of refraction of the beam is

A metal plate is exposed to light with wavelength lambda . It is observed that electrons are ejected from the surface of the metal plate. When a retarding uniform electric field E is imposed, no electron can move away from the plate farther than a certain distance d. Then the threshold wavelength lambda_(0) for the material of plate is ( e is the electronic charge, h is Planck's constant and c is the speed of light)
