Question

why do we use double slit to produce interferenc pattern​

Answer 1

Explanation:

Double slits produce two coherent sources of waves that interfere. (a) Light spreads out (diffracts) from each slit, because the slits are narrow. These waves overlap and interfere constructively (bright lines) and destructively (dark regions).

Answer 2

Answer:

In interference experiment we need two sources of light so that they can interfere otherwise we can't call it interference.

And to create two coherent sources forming double slit is the best method.
