A beam of unpolarised ligth is incident on a glass-air interface. Showing a suitable ray diagram,that light reflected from the interface is totally polarised,when `mu=tan i_B`,Where `mu` is the refractive index of glass with respect to air and `i_B` is the Brewster's angle.

A ray of light is incident at the glass-water interface at an angle i. It merges finally parallel to the surface of the water. Then, the value of mu_g would be(where mu_g is the refractive index of glass with respect to water)

Can reflection result in plane polarised light if the light is incident on the interface from the side with higher refractive index?

This angle of incidence at which relfeted ligth is totally polarised for reflection from air to glass(refractive index mu ),is:

What is an unpolarised ligth ?Explain with the help of a suitable ray diagram,how an unpolarised light can be polarised by reflection from a transparent medium.Write the expression for Brewster angle in terms of the refractive index of the denser medium.

A ray of light is incident on the surface of a glass plate of refractive index 1.536 at the polarising angle.Calculate the angle of refraction.

A ray is incident on the surface of glass plate of refractive index sqrt 3 . What is the value of angle of incidence, if reflected light is completely polarised?

White ligth is incident on the interface of glass and air as shown in the figure.If green light is just totally internally reflected,then the emerging ray in air contains. .

A beam of light of wavelength 400 nm is incident normally on a right angled prism as shown in fir.2.45. . It is observed that the light just grazes long the surface AC after falling on it.Give that there fractive index of the material of the prism varies with the wavelength as per the relation. mu=1.2 + b/(gamma^2) Calculate the value of b and the refractive index of the prism material for a wavelength gamma = 500 nm .Given theta=sin^(-1) 0.625 .
