Question

what is reflection and refrection???????????

Answer 1

REFLECTION: When light falling on a surface retraces back into the same medium , it is said to be reflected. REFRACTION: the phenomenon of deviation of light rays from their original path while passing from one medium to another due to change of speed of light in other medium is called refraction.

Answer 2

Answer:

When a wave travelling in a medium is incident on

a boundary with another medium, a part of it

returns into the original medium with a change in

its direction of propagation while a part of it is

transmitted into the second mediun. The phenom-

enon in which a part of the wave is retumed into the

original medium with reduction in its intensity and

energy is called reflection.
