Asingle-slit diffraction pattern is formed on a distant screen. if the width of the single slit through which light passes is reduced, what happens to the width of the central bright fringe? assume the angles involved remain small.

The width of the central bright fringe will increase

Explanation:

In a single-slit diffraction pattern, the distance of the nth-minimum from the central maximum on the screen is given by

where

is the wavelength of the wave

D is the distance of the screen from the slit

d is the width of the slit

The width of the central bright fringe is equal to twice the value of y=1 (first minimum), so:

And we see that it is inversely proportional to the width of the slit: therefore, if the width of the slit is reduced, the width of the central brigh fringe will increase.

be subject to a force andchange its motion

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
