The work function of Silver and sodium are `4.6 and 2.3 eV, ` respectively . The ratio of the slope of the stopping potential versus frequency plot for silver to that of sodium is

Explanation

To solve the problem, we need to analyze the stopping potential versus frequency plot for both silver and sodium. The stopping potential (Vs) is related to the frequency (ν) of the incident light and the work function (φ) of the metal.
