Nitrogen laser produces a radiation ...

Nitrogen laser produces a radiation at a wavelength of 337.1 nm if the number of photons emitted is `5.6 xx 10^(24)` calculate the power of this laser.

Text Solution

Verified by Experts

Emitted laser energy `(E ) = (hc )/(lambda)` and Number of photon =N laser energy `=E_(p)`
`:. , E_(p) = (Nhc )/( lambda)`
`=(5.6 xx 10^(24) 6.626 xx 10^(34) js 3.0 xx 10^(8) ms^(-1))/( (337 .1 xx 10^(9) m))`
`0.3302 xx 10^(7) `
`=3.302 xx 10^(6) J` emitted laser energy
