Question

physics Test 2 In a double slit experiment, if the separation between the two slits is 0.050 mm and the distance from the slits to a screen is 2.5 m, find the spacing between the first-order and second-order bright fringes when coherent light of wavelength 600 nm illuminates the slits.

Answer 1

Answer:0.015 m

Step-by-step explanation:

Given

distance between two slits(d)=0.050 mm

Distance between slit and screen=2.5 m

Wavelength
`(\lambda )=600 nm`

and distance between First order and second order
`=(D\lambda )/(2d)`

`=(2.5* 600* 10^(-9))/(2* 5* 10^(-5))`

`=15* 10^(-3)`

=0.015 m
