A photon and an electron (mass $\displaystyle m$ ) have the same energy $\displaystyle E$. The ratio ( $\displaystyle \lambda_{\text {photon }} / \lambda_{\text {electron }}$ ) of their de Broglie wavelengths is: ( $\displaystyle c$ is the speed of light)
Official answer
From NTA’s final answer key for this paper.
