Question

In Young’s experiment, how is the constructive interference produced on the screen?

Answer 1

Answer:

the difference in paths from the two slits to a point on the screen equals an integral number of wavelengths

Explanation:

Constructive interference occurs whenever the difference in paths from the two slits to a point on the screen equals an integral number of wavelengths (0, λ, 2λ,…). ... This interference pattern is caused by the superposition of overlapping light waves originating from the two slits.
