Light Reflectio...

Curved mirror whose reflecting surface faces towards the centre of the sphere, from which is considered to be a part of, is known as

Which of the following is a spherical lens?

A beam of light striking the surface of a glass plate from the air as shown in above figure.
If the angle between reflected beam and refracted beam is 90 degree, Find out the refractive index of the glass?

A glass slab has two long parallel faces. Light ray is incident on the glass slab and trace of light ray is drawn. Now glass slab is shifted parallel to the parallel faces. What will be the effect on the trace of light?

A ray of light is incident on the interface between water and glass at an angle i and refracted parallel to the water surface, then value of $$\mu_g$$, refractive index of glass will be:

A spherical lens has a focal length $$2\ cm$$. The lens will be

The diameter of the reflecting surface of spherical mirror is called ..............

Magnification of lens is:

The radius of the sphere of which the reflecting surface of a spherical mirror forms a part, is called ...............

A water film is formed on a glass-block. A light ray is incident on water film from air at an angle of $$\displaystyle { 60 }^{ \circ  }$$ with the normal. The angle of incidence on glass slab is
($$\displaystyle { \mu  }_{ g } = 1.5,{ \mu  }_{ w } = \frac { 4 }{ 3 } $$)
