Use the data gathered for the laser light through the diffractions grating in steps $10$ and $11$ and the expected value of the distance between slits you calculated at the start of this Data Analysis section to calculate a value for the wavelength of the laser light.

Step $10$:

$-$ Wavelength on Laser: $650$ nm

Step $11$:

$-$ Distance from the Center of Central Bright Spot to the Center of the First Order, Adjacent, Bright Spot: $0\mathrm{.}084$m

Data Analysis:

$-$ Distance Between Slits $($d$)$: $1\mathrm{.}895*10^-6$m
