Two coherent sources of wavelength ' $\lambda$ ' produce steady interference pattern. The path difference corresponding to $10^{\text {th }}$ order maximum will be
  1. $9.5 \lambda$
  2. $10.5 \lambda$
  3. $9\lambda$
  4. $10 \lambda$

Solution

Path difference for $n$th maximum is $n \lambda$. ~
