In the given figure, PQ and RS are two mirrors placed parallel to each other.
An incident ray AB strikes the mirror PQ at B, 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, two chords AB and CD intersect each other at the point P. Prove that AP*PB= CP*DP

In the given figure, two chords AB and CD intersect each other at the point P. Prove that DeltaAPC ~ DeltaDPB

In the given figure, two chords AB and CD of a circle intersect each other at the point P (when produced) outside the circle. Prove that DeltaPAC ~ DeltaPDB

In the given figure, two chords AB and CD of a circle intersect each other at the point P (when produced) outside the circle. Prove that PA*PB= PC*PD

Two plane mirror M_(1) "and" M_(2) are inclined to each other at 70^(@) . A ray incident on the mirror M_(1) at an angle theta fallls on M_(2) and is then reflected parallel to M_(1) for

Two mirrors are inclined at angle theta as shown in figure. Light rays are incident parallel to one of mirrors. Light will start retracing its path after the reflection if

Two concave mirrors each of radius of curvature 40cm are placed such that their principla axes are parallel to each other and at a distance of 1cm to each other. Both the mirrors are at a distance of 100cm to each other. Consider first reflection at M_(1) and then at M_(2) , find the coordinates of the image thus formed. Take location of object as the origin

Two thin slabs of refractive indices mu_(1) and mu_(2) are placed parallel to each other in the x-z plane. If the direction of propagation of a ray in the two media are along the vectors vec(r)_(1) = a hati +b hatj and vec(r)_(2) = c hati +d hatj then we have:

PQ type incident radiation and RS is the reflected ray. They are both parallel. So which mirror on the right makes this possible? There may be one or more reflections through the mirror.

A ray of light in incident along a vector hati + hatj - hatk on a plane mirror lying in y-z plane. The unit vector along the reflected ray can be
