The frequency of a photon, having energy $100eV$ is$(h = 6.6\,{10^{ - 34}}\,J{\rm{ - }}sec)$
$2.42 \times {10^{26}}Hz$
$2.42 \times {10^{16}}Hz$
$2.42 \times {10^{12}}Hz$
$2.42 \times {10^9}Hz$
According to Einstein's photoelectric equation, the graph between the kinetic energy of photoelectrons ejected and the frequency of incident radiation is
For photo-electric effect with incident photon wavelength $\lambda$, the stopping potential is $V _0$. Identify the correct variation$(s)$ of $V _0$ with $\lambda$ and $1 / \lambda$. $Image$
The momentum of the photon of wavelength $5000\,\mathring A$ will be
A radiation of energy $'E'$ falls normally on a perfectly reflecting surface. The momentum transferred to the surface is $( C =$ Velocity of light $)$
In photoelectric effect, if a weak intensity radiation instead of strong intensity of suitable frequency is used then
