Question:

The energy of a photon is equal to the kinetic energy of a proton. The energy of the photon is E. Let $λ_1$ be the de- Broglie wavelength of the proton and $λ_2$ be the wavelength of the photon. The ratio $λ_1/λ_2$ is proportional to the following

Options:

$E^0$

$E^{1/2}$

$E^{-2}$

$E^{-1}$

Correct Answer:

$E^{1/2}$

Explanation:

The correct answer is Option (2) → $E^{1/2}$
