Helium–neon laser light (λ = 632.8 nm) is sent through a 0.350-mm-wide single slit. what is the width of the central maximum on a screen 2.00 m from the slit?

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

Put the value into the formula

We need to calculate the width of the central bright fringe

Using formula of width

Put the value into the formula

Hence, The width of the central bright fringe is 7.24 mm.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
