A screen is placed a distance L from a single slit of width a, which is illuminated with light of wavelength ?. Assume L
the formula -
? = ws/D
Rearrange to get in terms of s(slit spacing)
s = ?D/w
Throw in your values (remember to convert to m)
The general formula to apply here is y/L = m(wavelength/a
We need delta y alone by subtracting, so...
y - y = (m2)(wavelength)L/a - (m1?)(wavelength)L/a
Since L, a and wavelength are not cocnstant, we get
(delta y) = (m2-m1)(wavelength)L/a
Solving for a gives us
a = (m2-m1)(wavelength)L/(delta y)
Rewritten, that is...

In a single slit diffraction experiment, the screen is placed 2.45m away from the slit. Light with a wavelength of 685nm forms a pattern on the screen and the fourteenth dark fringe form 76.0cm above center of the pattern. What is the width of the slit?
a) The double slit experiment, with slit width of 1mm and screen distance 3 meters, is performed with two different wavelengths of light. wavelength= 300 nm (violet light) and wavelength= 700 nm (red light). Find the difference in position on the screen of the fifth maximums between red and violet light. b) Repeat this but for the single slit diffraction experiment with apeture size of 2 mm and screen distance 4 meters.
