PhysicsEasysingle choice

In Young's double-slit experiment, spacing between the two slits is $0.1 m m$ . If the screen is kept at a distance of $1.0 m$ from the slits and the wavelength of light is $5000 Å$ , then the fringe width is

Options:

Answer:

Solution:

Fringe width is given by

$β = \frac{λ D}{d}$

$β = \frac{(5000 \times 1 0^{- 10}) \times 1}{0.1 \times 1 0^{- 3}} = 5 \times 1 0^{- 3}$

$β = 0.5 c m$
