In a ruby laser, laser light of wavelength 694.3 nm is emitted. The ruby crystal is 7.80 cm long, and the index of refraction of ruby is 1.75. Think of the light in the ruby crystal as a standing wave along the length of the crystal. How many wavelengths fit in the crystal? (Standing waves in the crystal help to reduce the range of wavelengths in the beam.) wavelengths
