Dual Nature of Radiation and Matter

The number of photons per second, on an average, emitted by a source of monochromatic light of wavelength 600 nm, when it delivers a power of 3.3×10−33.3 \times 10^{-3} watt, will be (h=6.6×10−34h = 6.6 \times 10^{-34} J s):

  1. A.101810^{18}
  2. B.101710^{17}
  3. C.101610^{16}✓
  4. D.101510^{15}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
