If the distance between two slits is 0.0620 mm find the angle between the second and third order bright fringe for light with a wavelength of 503nm.
Is the answer 0.48?
Find the angle for the k=2 max, then find the angle for k=3 max, ans subtract the angles to get the difference.
d sinTheta= k*l
I get 0.464932031 degrees. Check your work again, I could have made an error.
