Question

find an expression for the linear width of central maxima in diffraction pattern obtained from single slit.​

Answer 1

Answer:

The linear width of central maxima in a diffraction pattern obtained from a single slit is $\frac{2D\lambda}{d}$.

Explanation:

The linear width of central maxima in a diffraction pattern obtained from a single slit is given as,

$\beta=\frac{2D\lambda}{d}$           (1)

Where,

β=linear width of central maxima in single slit

D=distance of the slit from the screen

λ=wavelength of the light used in the diffraction pattern

d=distance between the slits

Answer 2

Answer:

In a Single slit diffraction pattern monochromatic light is passed through a single slit which has a central maximum and many smaller and dimmer maxima on either side.

Explanation:

The linear width of central maxima in a diffraction pattern by a single slit is given as,

β$=$$2D$λ/$d$

Where,

β=linear width of central maxima in single slit

D=distance between slit and screen

λ=wavelength of the light used in the diffraction pattern

d=distance between the slits
