(B) The fringe width $\beta$ in Young's double slit experiment is given by the formula $\beta = \frac{\lambda D}{d}$.Here,$\lambda$ is the wavelength of the light used,$D$ is the distance between the slits and the screen,and $d$ is the distance between the two slits.When the source of light changes from orange to blue,the wavelength $\lambda$ decreases because the wavelength of blue light is shorter than that of orange light.Since $\beta \propto \lambda$,as the wavelength $\lambda$ decreases,the fringe width $\beta$ (the distance between consecutive fringes) also decreases.

In Young's double slit experiment,if the source of light changes from orange to blue,then

In a double slit experiment,the distance between slits is increased $10$ times whereas their distance from the screen is halved,then what is the fringe width?

Write the formula for fringe width.

Light of wavelength $6000 \,\mathring A$ is incident on two slits. The distance between the slits is $0.1 \, cm$ and the screen is placed at a distance of $1 \, m$ from them. What is the distance between two consecutive minima in $mm$?

In Young's double-slit experiment,the angular width of the fringes formed on the screen is $\pi / 200$. If light of wavelength $4800 \, \mathring{A}$ is used,find the distance between the slits.

In Young's double-slit experiment,an interference pattern is obtained on a screen by light of wavelength $6000 \ \mathring A$,coming from coherent sources $S_1$ and $S_2$. At a certain point $P$ on the screen,the third dark fringe is formed. Then the path difference $S_1P - S_2P$ in microns is:
