Q1

The threshold frequency of a metal is \(f0\). When the light of frequency \(2{f}_{0}\) is incident on the metal plate, the maximum velocity of photoelectrons is \({v}_{1}\). When the frequency of incident radiation is increased to \(5{f}_{0}\). The maximum velocity of photoelectrons emitted is \({v}_{2}\). The ratio of \({v}_{2}\). The ratio of \({v}_{1}\) to \({v}_{2}\) is:

[JEE Main 2023, 1 Feb (Shift 2)]

a

\(\frac{{v}_{1}}{{v}_{2}}=\frac{1}{2}\)

b

\(\frac{{v}_{1}}{{v}_{2}}=\frac{1}{8}\)

c

\(\frac{{v}_{1}}{{v}_{2}}=\frac{1}{16}\)

d

\(\frac{{v}_{1}}{{v}_{2}}=\frac{1}{4}\)
