Q1

The threshold frequency of metal is \(f_0\). When the light of frequency \(2 f_0\) is incident on the metal plate, the maximum velocity of photoelectron 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 \(v_1\) to \(v_2\) is:

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

\(
\frac{v_1}{v_2}=\frac{1}{4}
\)
