A vertical ray of light strikes the horizontal surface of some water:
a) What is the angle of incidence?
b) What is the angle of refraction?

A ray of light strikes the glass slab at an angle of 50^(@) . What is the angle of incidence ?

A ray of light strikes the glass slab at an angle of 50^@ .What is the angle of incidence?

When a light ray enters into glass medium from water at an angle of incidence 0^(@) , what would be the angle of refraction?

A ray of light is incident on the surface of a glass plate of R.I 1.55, at the polarising angle of incidence. Calculate the angle of refractions.

A plane mirror lies face up, making an angle of 15^@ with the horizontal .A ray of light shines down vertically on the mirror .What is the angle of incidence? What will be the angle between the reflection ray and the horizontal?

A ray strikes the mirror normally, what is the angle of incidence?

A ray of light incident on the horizontal surface of a glass slab at an angle of incidence ‘i’just grazes the adjacent vertical surface after reflection. Compute the critical angle and refractive index of glass
