Vedclass · Answer

(C) According to Einstein's photoelectric equation: $K_{max} = h v - \Phi_0$, where $K_{max}$ is the maximum kinetic energy of the emitted photoelectrons, $h$ is Planck's constant, $v$ is the frequency of incident radiation, and $\Phi_0$ is the work function of the metal.Since $K_{max} = e V_s$, where $e$ is the charge of an electron and $V_s$ is the stopping potential, we can write: $e V_s = h v - \Phi_0$.Rearranging for the stopping potential: $V_s = \frac{h}{e} v - \frac{\Phi_0}{e}$.From this linear equation, it is evident that the stopping potential $(V_s)$ is directly proportional to the frequency $(v)$ of the incident radiation.Therefore, if the frequency $(v)$ is increased, the stopping potential $(V_s)$ also increases.

In the photoelectric effect experiment, if the frequency of incident radiation $(v)$ is increased, keeping all other factors constant, what happens to the stopping potential $(V_s)$, given $(v > v_0)$ where $(v_0)$ is the threshold frequency?

When a metallic surface is illuminated with radiation of wavelength $\lambda$,the stopping potential is $V$. If the same surface is illuminated with radiation of wavelength $2\lambda$,the stopping potential is $\frac{V}{4}$. The threshold wavelength for the metallic surface is:

The stopping potential for a source of wavelength $4000\, \mathring{A}$,when kept at a distance of $10\, \text{cm}$,is $1.5\, \text{V}$. If now the distance of the source is increased to $20\, \text{cm}$,then the stopping potential will be ............... $\text{V}$.
