The velocity of light in a medium is half its velocity in air. If a ray of light emerges from such a medium into air, the angle of incidenc, at which it will be totally internally reflected, is

When a ray of light enters from one medium to another then its velocity in second medium becomes doubled. The maximum value of angle of incidence so that total internal reflection may not take place will be

A sound wave travelling with a velocity V in a medium A reaches a point on the interface of medium A and medium B . If the velocity in the medium B be 2 V , then the angle of incidence for total internal reflection of the wave will be greater than:

When a ray of light passes from air medium to denser medium then the refractive index is

A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence is

A ray of light is incident on a medium boundry at polarising angle such that its deviation is 24^(@) , then angle of incidence is :
