Answer:
The width of the central bright fringe is 7.24 mm.
Explanation:
Given that,
Wavelength = 632.8 nm
Width d= 0.350 mm
Distance between screen and slit D= 2.00 m
We need to calculate the distance
Using formula of distance
[tex]y_{m}=\dfrac{\lambda D}{d}[/tex]
Put the value into the formula
[tex]y_{m}=\dfrac{632.8\times10^{-9}\times2.00}{0.350\times10^{-3}}[/tex]
[tex]y_{m}=3.62\ mm[/tex]
We need to calculate the width of the central bright fringe
Using formula of width
[tex]width = 2\times|y_{m}|[/tex]
Put the value into the formula
[tex]width=2\times3.62[/tex]
[tex]width = 7.24\ mm[/tex]
Hence, The width of the central bright fringe is 7.24 mm.
