When a ray of light travels perpendicular to the surface of separation of the two mediums, there is ............... (maximum/no) refraction.

When a ray of light strike the surface of seperation of two optical media _____ it does not suffer any refraction.

When a ray of light from air enters a denser medium, it :

A ray of light is incident as a normal ray on the surface of separation of two different mediums. What is the value of the angle of incidence in this case ?

A ray of light travels from an optically denser to rarer medium. The critical angle of the two media is C. The maximum possible deviation of the ray will be

The ray of light after changing its direction in the second medium after refraction is called ................... (reflected ray/refracted ray).

When a ray of light travels obliquely from a rarer medium to a denser medium, it bends away from the normal.

When a ray of ordinary light is incident on the surface of separation of two media at polarizing angle, show with the help of a labelled diagram that reflected ray and the refracted ray are mutually perpendicular to each other.

Figure shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is

(a) State Snell's law of refraction of light. (b) A transparent medium A floats on another transparent medium B. When a ray of light travels obliquely from A into B, the refracted ray bends away from from the normal. Which of these two media A or B are optically denser and why ?

What is the cause of refraction of light when it passes from one medium to another ?
