Refraction & Reflection of Light

Assertion : If light is polarised by reflection, then the angle between reflected and refracted ray is 180^@ . Reason : Brewester's law : mu = tan i_p .

Select the correct statement about the reflection and refraction of a wave at the interface between the medium 1 and 2 the

If the angle of reflection is 45^@ , what is the angle between the incident ray and the reflected ray?

A ray of light-is incident on glass at the polarising angle ip. Find the angle between the reflected and refracted rays.

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index n),

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index n),

A ray of light entering from air to glas (mu=1.5) is partly reflected and partly refracted. lf the reflected and refracted rays are at right angles to each other, the angle of refraction is

When light is polarised by reflection from a transparent surface. a) reflection and refracted rays are mutually perpendicular b) both reflected and refracted rays are plane polarised c) refraction ray is partially polarised d) the R.I., of transparent surface is equal to tangent of Brewster.s angle

Write two advantages of a reflecting telescope over a refracting telescope.
