Question

What happens to the phase difference between two incoherent sources?

विकल्प

• It changes rapidly and randomly with time

• It is always \[(2n+1)\pi\]

• It remains constant

• It is always \[2n\pi\]

Answer 1

For incoherent sources, the phase difference changes rapidly and randomly with time. Because it does not remain constant, the interference pattern is not stable.
