A ray of light travelling in water falls at right angles to the boundary of a parallel-sided glass block. The ray of light:

A ray of light travelling in a glass merges into air, it will bend:

A ray of light travelling obliquely from glass to air :

When a ray of light travelling in glass enters into water obliquely:

A ray of light travelling in air goes into water. The angle of refraction will be:

A ray of light travelling in air is incident on a parallel-sided glass slab(or rectangular glass slab). Draw a ray-diagram indiciating the change in its path in glass.

A ray of light travelling from glass to air is incident at 50^(@) from the glass air boundary . What is the angle of deviation if the critical angle is 42^(@) ?

A ray of light travelling in air is incident on the surface of glass slab at an angle of 40^(@) . If the ray is deviated through 18^(@) , determine critical angle for the glass-air interface.

A ray of light travelling in air strikes the surface of glass at angle of 45^(0) . The angle of refraction in the glass will be :
