A light ray of wavelength $\lambda$ is passing through a pin hole of diameter $D$ and the effect is observed on a screen placed at a distance $L$ from the pin hole. The approximations of geometrical optics are applicable, if
  1. $D \leq \lambda$
  2. $\frac{L \lambda}{D^2}=1$
  3. $\frac{L \lambda}{D^2}< < 1$
  4. $\frac{L \lambda}{D^2}>>1$
