Question

The number of photons of light having wave number x in 1J of energy source is
(Planck's constant = h, velocity of light = c)​

Answer 1

Answer:

Energy Radiation = n × hc/lamda.

wave number= c/lamda

therfore X=c/lamda

Substitute the X

Energy radiation = n × hx

so

1=n×hX

1/hX = number of photons
