Nitrogen laser produces a radiation at a wavelength of 337.1 nm



Q.46:- Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is 5.6×1024, calculate the power of this laser.

 

 

Answer:-



E = Nhν = Nhc/λ = (5.6×1024)×(6.626×10-34 Js×3.0×10ms-1)/337.1×10-9 m = 3.3×10J
