Any ray of light traveling parallel to the principal axis, after reflection pass through the focus or appears to diverge from the focus. ..

Refraction of Light - Let us now see what happens when a ray of light is incident on the boundary separating the two media having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second medium. The diagram shows how the l..

It is named after the mathematician George Papy. The elements of one set are placed in one circle and the elements of the other set are placed in the second circle. Arrows indicate the passing of elements of set A to set B or set B to set A. (i) A x B = {(3, 2), (3, 4), (3, 6), (5, 2), (5, 4), (5,..
