A photon in motion has a mass
$c/h\nu $
$h/\nu $
$h\nu $
$h\nu /{c^2}$
(d)$E = h\nu = m{c^2}\, \Rightarrow \,\,m = \frac{{h\nu }}{{{c^2}}}$
Which of the following statement is not correct
The light of two different frequencies whose photons have energies $3.8 \,eV$ and $1.4 \,eV$ respectively, illuminate a metallic surface whose work function is $0.6 \,eV$ successively. The ratio of maximum speeds of emitted electrons for the two frequencies respectivly will be
An electron and a photon each have a wavelength of $1.00\; nm$. Find
$(a)$ their momenta,
$(b)$ the energy of the photon, and
$(c)$ the kinetic energy of electron.
Given below are two statements
Statement$-I :$ Two photons having equal linear momenta have equal wavelengths.
Statement$-II :$ If the wavelength of photon is decreased, then the momentum and energy of a photon will also decrease.
In the light of the above statements, choose the correct answer from the options given below.
