[SOLVED] Double slit equations
In an experiment, blue light with a wavelength of 645 nm is shone through a double-slit and lands on a screen that is located 1.35 m from the slits. If the distance from the centre maximum to the 8th order bright fringe is 2.6 cm, calculate the distance between the two slits.
Here is what I did:
wavelength=6.45*10^-7 m
L=1.35 m
m=8
X=0.026m
I used X/L = m*wavelength/d to find d.
Is this right?
