1 Dual Nature Of Radiation And Matter
A monochromatic light of frequency $$v = \frac{1}{6.63} \times 10^{16}$$ Hz is produced by a laser. The power emitted is $$P = 10^{-2}$$ W. The average number of photos per second emitted by the source is
1) $$\frac{1}{(6.63)^2} \times 10^{16}$$ 2) $$(6.63)^2 \times 10^{16}$$ 3) $$10^{20}$$ 4) $$10^{16}$$
