Spectra Laser
August 2nd, 2008
The carbon dioxide laser, the energy difference between the two lasers is 0.117eV.?
a) what is the frequency emmitted?
b) in what part of the EM spectrum is such radiation found?
E = h*nu
E = energy = 0.117 eV
h = Planck’s constant = 4.14×10^(-15) eV.s
frequency = nu = E/h
plug and play… units will be Hz (1/s)
for the region of the EM spectrum, see
