what is diffraction and interface

Answers

Answered by ambikesh1312

interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude.
Diffraction refers to various phenomena that occur when a wave encounters an obstacle. In classical physics, the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.

Anonymous: what is superimpose

ambikesh1312: Superimposition was one of the magical effects employed by early filmmakers. Using "mirror shots", with semitransparent mirrors set at 45° angles to the scene, they would superimpose shadowy images of ghosts or scenes from a character's past onto scenes from the present. Superimposing your own ideas on something, such as a historical event, has to be done carefully, since your ideas may change whenever you learn something new about the event.

Hello mate,

1) Two separate wave fronts originating from two coherent sources produce interference.Width of the fringes is equal in interference
2) Secondary wavelets originating from different parts of the same wave front constitute diffraction. In diffraction they are never equal.

Thus the two are entirely different in nature.
Hope that you will get this .

Have a great future :)
