Nitrogen laser produces a radiatio at a ...

Nitrogen laser produces a radiatio at a wavelength of 337.1 nm. If the number of photons emitted is `5.6xx10^(24)`, calculate the power of this laser.

Text Solution

Verified by Experts

`E=Nhv=Nh(c)/(lamda)`
`=((5.6xx10^(24))xx(6.626xx10^(-34))xx(3.0xx10^(8)))/((337.1xx10^(-9)))`
`=3.3xx10^(6)J`
