The fringe width will remain unchanged.

(D) The fringe width $\beta$ is given by the formula $\beta = \frac{\lambda D}{d}$.Here,$\lambda$ is the wavelength of the monochromatic light,$D$ is the distance between the slits and the screen,and $d$ is the distance between the two slits.When a glass plate is introduced in the path of one of the beams,it introduces an additional path difference,which causes a shift in the entire interference pattern.However,the parameters $\lambda$,$D$,and $d$ remain unchanged.Therefore,the fringe width $\beta$ remains constant and does not change.

Class 12 Physics Wave Optics Young's Double Slit Experiment (YDSE)

Easy

In Young's double-slit experiment,monochromatic light is used to illuminate two slits $A$ and $B$. Interference fringes are obtained on a screen in front of the slits. Now,if a thick glass plate is placed in the path of light from one of the slits,then:

A
The fringes will disappear.
B
The fringe width will decrease.
C
The fringe width will increase.
D
The fringe width will remain unchanged.

Young's Double Slit Experiment (YDSE)

In a Young's double slit experiment, the slits are $2 \,mm$ apart and are illuminated with a mixture of two wavelengths ${\lambda _1} = 750 \,nm$ and ${\lambda _2} = 900 \,nm$. The minimum distance from the common central bright fringe on a screen $2 \,m$ from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other is.....$mm$
