A near U.V. photon of 300 nm is absorbe by a gas is red then remitted as two photons. One photon is red with wavelength 760 nm. Hence wavelength of the second photon is

Text Solution

Verified by Experts

Energy abosrbed=sum of energy of two quanta.
`(hc)/(300xx10^(-9))=(hc)/(760xx10^(-9))+(hc)/(lamdaxx10^(-9))`
On solving, we get,
`overline(v)("wave number")=(1)/(lamda)=2.02xx10^(-3)m^(-1)`.
