Question

The vapours of Hg absorb some electron accelerated by a potential di­fference of 5.0 V as a result of which light is emitted. If the full energy of single incident electron is supposed to be converted into light emitted by single Hg-atom, then the wavelength of the emitted light is

Options

A.2480 nm
B.248 nm
C.6200 nm
D.620 nm

Solution

$\lambda = \frac{1240}{5} = 248\text{ nm}$
