(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

With regard to Young's double slit experiment, locate the position above the central axis of the 3rd bright fringe for light of wavelength 500nm incident on slits separated by 0.1mm, when a thin (0.001mm) parallel sheet of glass of index 1.4 is placed in front of the slits. The distance from the slits to the screen is 2 meters.

2. Relevant equations

Where do I use the distance to the screen (the 2 meters)? Am I missing something or is it just useless information??

3. The attempt at a solution

a * sin([tex]\theta[/tex]) = (m*[tex]\lambda[/tex]) - (nd)

a=.0001m

m=3

[tex]\lambda[/tex]=500nm

n=1.4

d=1*10^-6

[tex]\theta[/tex] = 0.001
