Light of wavelength 610 nm is incident on a slit of width 0.20 mm, and a diffraction pattern is produced on a screen that is 1.5 m from the slit. What is the distance of the second dark fringe from the center of the bright fringe>?

distance of the second dark fringe from the center of the bright fringe is 0.92 cm

Explanation:

given data

wavelength = 610 nm = 610 × m

slit of width = 0.20 mm = 0.20 × m

distance between screen and slit = 1.5 m

solution

we apply here formula for second minima that is

L =   ...................1

and here for second minima n is 2

put here value we get

L =    

L = 0.915 × m

so distance of the second dark fringe from the center of the bright fringe is 0.92 cm

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.
