Application +4 | -1

The de-Broglie wavelength of an electron is the same as that of a photon. If velocity of electron is

25 \%

of the velocity of light, then the ratio of K.E. of electron and K.E. of photon will be

View answer and explanation

Correct option: A

\frac{1}{8}

Option A (

\frac{1}{8}

) is correct because the ratio of kinetic energies can be found by comparing the kinetic energy of the electron to the energy of the photon, considering their relationship through de-Broglie wavelength.
