Problem 38.5: Wavelength of light through a diffraction grating

Please wait for the animation to completely load.

This animation models a diffraction grating that is a series of parallel slits in a material. You can change the slit spacing and see the first- and second-order maxima (position is given in centimeters and angle is given in degrees). Restart. What is the wavelength of the light passing through the diffraction grating?
