In the given Figure , PQ and RS are two mirrors placed parallel to each other . An incident ray AB striker the mirror PQ at B, the reflected ray moves along the path BC and strikes the mirror RS at C and again reflects back along CD. Prove that `AB|| CD.`

In the given figure PQ & RS are two parallel tangents to a circle o and another tangent AB with point of contact C intersecting PQ at A and RS at B. Prove that angleAOB = 90^@

Two mirrors meet at right angles . A ray of light is incident on one at an angle of 30^@ as shown in figure .Draw the reflected ray from the second mirror.

Why does ray of light passing through the centre of curvature of a concave mirror gets reflected along the same path (ray retraces its path) ?

In the following figures, the mirror line (i.e., the line of symmetry) is given as a dotted line. Complete each figure performing reflection in the dotted (mirror) line. (You might perhaps place a mirror along the dotted line and look into the mirror for the image). Are you able to recall the name of the figure you complete?
