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?

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.

What is the polarising anle of a medium of refractive index sqrt3 ?

At what angle of incidence will the light reflected from glass (=1.5) be completely polarised?

Calculate the angle of emergence (e) of ray of light incident normally on the face AC of a glass prism ABC of refractive index sqrt 3 . How will the angle of emergence change qualitatively if the ray of light emerges form the prism into a liquid of refractive index 1.3 instead of air?

Figure 9.35 shows a cross-section of a glass fibre of refractive index 1.68. The outer covering of the pipe is made of a material of refractive index 1.44. What is the range of the angles of the incident rays with the axis of the pipe for which total reflections inside the pipe take place, as shown in the figure. :

A ray of light is incident on a prism ABC of refractive index sqrt3 as shown in Fig.3.14. Find the angle of incidence for which the deviation of light ray by the prism ABC is minimum. .

What is the angle of incidence when incident ray falls normal to the mirror?

A ray of liht is incident on the face AB of a glass prism ABC having the vertex angle A equal to 30^@ .The face AC is silvered and a ray of ligth is incident on the face AB,such that it etraces its path.If efractive index of the glass is 3^(1/2) ,calculate the ngle of incidence on the face AB.
