In Young's double-slit experiment, $12$ fringes are obtained to be formed in a certain segment of the screen when the light of wavelength $600 nm$ is used. If the wavelength of light is changed to 400 nm, the number of fringes observed in the same segment of the screen is given by

Options:

Answer:

Solution:

In case of overlapping of fringes.

$n β = c o n s t e n t$

$n_{1} λ_{1} = n_{2} λ_{2}$

$∴ n_{2} = \frac{n_{1} λ_{1}}{λ_{2}} = \frac{12 \times 600}{400} = 18$
