What is interference? Define its types.
(N/A) The phenomenon of the superposition of two waves is called interference.
It has two types:
$(1)$ Constructive interference
$(2)$ Destructive interference
$(1)$ Constructive interference: When the crest of one wave is superposed on the crest of another wave,or the trough of one wave is superposed on the trough of another wave,the amplitudes add up for the resultant wave. This is called constructive interference.
$(2)$ Destructive interference: When the crest of one wave is superposed on the trough of another wave,or the trough of one wave is superposed on the crest of another wave,the amplitudes subtract for the resultant wave. This is called destructive interference.
