A carbon dioxide laser is an infrared laser. A CO2 laser with a cavity length of 53.00 cm oscillates in the m = 100,000 mode. What is the wavelength of the laser beam?

5.3 * 10^-4 m or 0.0000053m

Explanation:

Wavelength is given by 2L/m

Where m is the waves bewtween the cavity mirrors which is 100000

L is the cavity length which is 53.00 cm

53/100 (convert to meter) = 0.53m

Therefore the wavelength is (2 * 0.53m) / 100,000

=0.0000053

= 5.3 * 10^-6 m
