Upon using Thomas Young's double slit experiment to obtain measurements, the following data was obtained. Use this data to determine the wavelength of light being used to create the interference pattern. DO this in 3 different ways!
- The Angle to the Eighth maximum is 1.12 deg.
- The distance from the slits to the screen is 3.02 m
- The distance from the first minimum to the fifth minimum is 2.95 cm
- The distance between the slits is 0.00025 m
The Attempt at a Solution
The distance from the first minimum to the fifth minimum is 2.95 cm .. therefore
Δx=0.0074 m ( i converted it)
Im unsure about 4 x if anyone can shed any light on that that would be cool
λ=(0.0074) (0.00025)/ (3.02)
λ= 612 nm
as for this one I dont know if I should use the Xm or Xn equation..I used
λ= 610 nm
Number seems plausible but it also does when I use the Xn equation
thanks for any help in advance
