## Homework Statement

To confirm the wavelength of a new laser, a scientist prepares a diffraction grating with a distance of 5.00 x 10^-6 m between slits and places it in front of the laser which is 1.50 m in front of a screen. The scientist measures the distance from the central maxima to the second bright fringe, which is 0.33 m. What is the wavelength of the laser?

d = 5.00 x 10^-6 m

L = 1.50 m

n = 2

x = 0.33m

## Homework Equations

λ= xd/nL

λ= sinθ(d)/n

## The Attempt at a Solution

λ = xd/nL

= (0.33m)(5.00 x 10^-6m) / (2)(1.50)

= 5.5 x 10^-7 m
