PhysicsEasysingle choice

The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double - slit experiment is

Options:

Answer:

Solution:

For maxima, $d s i n θ = n λ$

$\Rightarrow 2 λ s i n θ = n λ$

$\Rightarrow 2 s i n θ = n$

$∴ s i n θ = \frac{n}{2}$

$∵ s i n θ < 1$

$\Rightarrow \frac{n}{2} < 1$

$\Rightarrow n < 2$

$n = 0,1$ maximum number of possible maxima = 3

$n = 0, \pm 1$
