Light of wavelength 633 nm from a distant source is incident on a slit 0.750 mm wide, and the resulting diffraction pattern is observed on a screen 3.50 m away. what is the distance between the two dark fringes on either side of the central bright fringe?

y=5.908 mm

Explanation:

Given data

wavelength (λ)= 633nm

d(distant source is incident on a slit)=0.750mm

D(diffraction pattern is observed on a screen)=3.50 m

To find

y(What is the distance between the two dark fringes on either side)=?

Solution

For a dark fringe to form

dy/D=λ

so

y=(Dλ)/deq(1)

Put values of D,λ and d in eq(1) we get

y={3.50×(633×10⁻⁹)}/(0.750×10⁻³)

y=2.954mm

So the total distance between dark fringes on either side is 2×y

so final distance is

y=5.908 mm

Hope This Helps Have A Wonderful Day/Night

Explanation:

The object continues to fall, but with NO ACCELERATION! Notice that there is no net force if the upward and downward forces are equal. Objects of equal size different masses. ... But, it will accelerate longer than the hollow ball, and its terminal velocity will be greater.
