Radiation corresponding to the transition

\mathrm{n}=4

\mathrm{n}=2

in hydrogen atoms falls on a certain metal (work function

=2.0 \mathrm{eV}

). The maximum kinetic energy of the photoelectrons will be:

View answer and explanation

Correct option: A

0.55 \mathrm{~eV}

Option A (

0.55 \mathrm{~eV}

) is correct because the maximum kinetic energy of the photoelectrons is the energy of the incident radiation minus the work function of the metal.
