(A) Comparing Einstein's photoelectric equation $\frac{1}{2}mv_{\max}^2 = hf - \phi_0$ with the linear equation $y = mx + c$,where $y = \frac{1}{2}mv_{\max}^2$,$x = f$,$m = h$,and $c = -\phi_0$.The slope of the graph is Planck's constant $h$,which is a universal constant and is independent of the nature of the metal or the intensity of the incident radiation.

Einstein's Photoelectric Equation and Energy Quantum of Radiation

When photons of energy $hv$ fall on a metal plate of work function $W_0$,photoelectrons of maximum kinetic energy $K$ are ejected. If the frequency of the radiation is doubled,the maximum kinetic energy of the ejected photoelectrons will be

Monochromatic radiation of wavelength $640.2 \;nm$ $(1 \;nm = 10^{-9} \;m)$ from a neon lamp irradiates a photosensitive material made of caesium on tungsten. The stopping voltage is measured to be $0.54 \;V$. The source is replaced by an iron source and its $427.2 \;nm$ line irradiates the same photo-cell. Predict the new stopping voltage (in $V$). (in $;V$)

$A$ point source of light emits photons of energy $4.8 eV$ at the rate $10^5$ photons per second. These photons are incident on a photo-sensitive sphere of work function $2.8 eV$ and radius $9 mm$. The sphere is initially neutral and the emitted photoelectrons are instantly swept away. The time after which the photoelectric emission stops is (in $s$)
