LASER Problems! HELP NEEDED!
1. The carbon dioxide laser usually emits at 10.6 um in the IR. Typically such a device puts out a continuous emission of from a few watts to several kilowatts. Determine the energy difference in eV between the two laser levels for this wavelength.
2. A certain variation of He-Ne laser operates btwn two levels that are 3.655 x10^-19J apart. What color is the beam? comupte the wavelength.
delta(E)=hc/^
^=wavelength
1. answer is .117eV ..(6.63x10^-34)(3x10^8)/(10.6x10^-6)??but didn't get it
2. answer is 543.5 nm( green)...3.655 x10^-19J =hc/^
Please HELP! THanks!
