Question

The frequency of incident light falling on a photosensitive metal plate is doubled, the kinetic energy of the emitted photoelectrons is

• A. Unchanged
• B. Less than doubled
• C. Double the earlier value
• D. More than doubled

Answer 1

The correct option is D More than doubled

$v\to 2v$ $hv-h{v}_o=K{G}_{max}$
So, $K{G}_{max}>2K{G}_{max}$
as $h{v}_o$ is constant
