A mirror and source of light are situated at the origin O and a point on OX respectively. A ray of light from the source strikes the mirror and is reflected. If the DRs of the normal to the plane of mirror are 1,-1,1, then DCs for the reflacted ray are :

A mirror and a source of light are situated at the origin O and at a point on O X , respectively. A ray of light from the source strikes the mirror and is reflected. If the direction ratios of the normal to the plane are 1,-1,1, then find the D C s of the reflected ray.

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

The ray of light that strikes or falls on a reflecting surface

Three plane mirrors are placed such that the angle between the first and second or second and third is the same theta . A light striking the first mirror, after reflection at the three mirrors emerges opposite to the initial direction. The value of theta can be

A ray of monochromatic light enters a liquid from air as shown in the diagram given below: Copy the diagram and show in the diagram the path of the ray of light after it strikes the mirror and reenters the medium of air.

A horizontal ray of light passes through a prism of index 1.50 and apex angle 4^(@) and then strikes a vertical mirror , as shown in the figure. Through what angle must the mirror be rotated if after reflection the ray is to be horizontal?

When a ray of light strikes a plane mirror along the normal, the angle of incidence is :

A ray of light strikes a plane mirror at an angle of incidence 45^@ as shown in Figure . After reflection,l the ray passes through a prism of refractive indes 1.5 whos apex angle is 4^@ . Through what angle must the mirror be rotated it total deviation of the ray be 90^@ ?
