From: AIEEE 2011

Question

A gas absorbs a photon of 355 nm and emits at two wavelengths. If one of the emissions is at 680 nm, the other is at :

Choose an option

Show full solutionCorrect option: B
Correct answer
B743 nm

Step-by-step explanation

Here a photon is divided into two photons of different wavelength.

According to the law of conservation of energy,

Energy of photon before dividing into two parts = Energy of first photon + Energy of second photon







nm = 743 nm
