Question

Correct representation of stopping potential $\left(V_0\right)$ with respect to frequency $\left(\nu \right)$ of radiation is

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

According to Einstein's photoelectric equation,

$e{V}_0=E-\varphi =h\nu -\varphi$

$\Rightarrow V_0=\frac{h}{e}\nu -\varphi$

Comparing the above relation with the equation of straight line,
$y=mx-c$

Therefore, the graph between $V_0$ and $\nu$ will be a Straight line with a positive slope and negative $y$ intersect.


Hence, option $\left(A\right)$ is correct.
