Question:medium
A monochromatic light of frequency \( \nu = \frac{1}{6.63} \times 10^{16} \) Hz is produced by a laser. The power emitted is \( P = 10^{-2} \) W. The average number of photons per second emitted by the source is
A monochromatic light of frequency \( \nu = \frac{1}{6.63} \times 10^{16} \) Hz is produced by a laser. The power emitted is \( P = 10^{-2} \) W. The average number of photons per second emitted by the source is
Show Hint
Always divide total power by energy per photon.
