At the first minimum adjacent to the central maximum of a single-slit diffraction pattern, the phase difference between the Huygen's wavelet from the edge of the slit and the wavelet from the midpoint of the slit is:NEET 2015 (Phase 2)

Options:

Answer:

Solution:

For first minima

$A P - B P = λ$

$A P - M P = \frac{λ}{2}$

So phase difference $= \frac{2 π}{λ} \times \frac{λ}{2} = π$
