relation between photons emitted and power of source

Answers (1)

Hello dear student,

There are two things. More photons means a brighter beam. power (Energy/sec) is proportional to the number of photons/sec.

Photons with shorter wavelengths and higher frequencies have more energy. That is a bluer beam has more power.

So P=nhνP=nhν where n is the number of photons/sec.
