For central maximum, path difference is zero for both coherent sources in interference. Hence, phase difference =(2 π/λ) × path difference =(2 π/λ) × 0=0

zero

$π$

$3 π /2$

$π /2$

For central maximum, path difference is zero for both coherent sources in interference.
Hence, phase difference $= \frac{2 π}{λ} \times$ path difference
$= \frac{2 π}{λ} \times 0 = 0$

3π/2

π/2

For central maximum, path difference is zero for both coherent sources in interference. Hence, phase difference =λ2π​× path difference =λ2π​×0=0

For central maximum, path difference is zero for both coherent sources in interference.
Hence, phase difference $= \frac{2 π}{λ} \times$ path difference
$= \frac{2 π}{λ} \times 0 = 0$
