Asingle slit diffraction pasttern has the central maximum width of 1 cm. given the wavelength of 500 nm and slit width of 0.01 mm, what is the distance from the slit to the observation screen? 1 m
0.1 m
71 cm
0.71 m
none of the above?

distance between slit and screen, d = 0.1 m

Given:

slit width, x =

width of central maximum, t = 1 cm

wavelength,

Explanation:

The first minima will be at the position t:

t =

Now, using the formula:

xsin

where

n = 1

xsin

sin

sin

Now, calculation of distance between slit and screen, d:

as technology advances, new experiments often expose problems in accepted theories. c
