Question

define refraction briefly

Answer 1

HEY MATE....

Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.

Answer 2

hii frnd ur answer is here....____

Refraction is the change in direction of wave propagation due to a change in its transmission medium.



An object (in this case a pencil) part immersed in water looks bent due to refraction: the light waves from X change direction and so seem to originate at Y. (More accurately, for any angle of view, Y should be vertically above X, and the pencil should appear shorter, not longer as shown.)
