True or false
A transparent medium is a good transmitter of light.

The value of the Bewster angle for a trnsparent medium is different for lights of different colours.

The critical angle between a given trasparent medium and air is denoted by C.A ray of light in air medium enters this transprent meidum at an angle of incidence equal to polarising angle p.Deduce a relation for the angle of refraction in terms of C.

True and False Type Questions ABO is a good example of multiple allele.

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 travelling in a transparent medium of refractie index mu falls on a surface separatign the medium from air at an angle of incidence of 45^@ .For which of the following velues of mu ,the ray can indergo total internal reflection?

An initially parallel cylindical beam travels in a medium of refractive index mu(I)=mu_0+mu_2I ,where mu_0 and mu_2 are positive constants and I is the intensity of the light beam.The intensity of the light beam is decreasing with increasing radius. The speed of the light in the medium is

Write True or False: Heliophytes are plants growing in lower light intensities.

When a ray of light passes through a parallel slab of transport medium, then show that angle of incidence is equal to angle of emergence.
