There are ${n_1}$ photons of frequency ${\gamma _1}$ in a beam of light. In an equally energetic beam, there are ${n_2}$ photons of frequency ${\gamma _2}$. Then the correct relation is
$\frac{{{n_1}}}{{{n_2}}} = 1$
$\frac{{{n_1}}}{{{n_2}}} = \frac{{{\gamma _1}}}{{{\gamma _2}}}$
$\frac{{{n_1}}}{{{n_2}}} = \frac{{{\gamma _2}}}{{{\gamma _1}}}$
$\frac{{{n_1}}}{{{n_2}}} = \frac{{\gamma _1^2}}{{\gamma _2^2}}$
The time taken by a photoelectron to come Out after the photon strikes is approximately
Write characteristic of photon or How photon of electromagnetic radiation can be represented ?
The photoelectric effect can be understood on the basis of
When monochromatic radiation of intensity $I$ falls on a metal surface, the number of photoelectrons and their maximum kinetic energy are $N$ and $K$ respectively. If the intensity of radiation is $2I$, the number of emitted electrons and their maximum kinetic energy are respectively
