A photon and an electron (mass $m$ ) have the same energy $E$ . The ratio ( $λ_{photon} / λ_{electron}$ ) of their de Broglie wavelengths is: (c is the speed of light)NEET 2025

Options:

Answer:

Solution:

Photon & electron have same energy E $\frac{λ _{photon}}{λ _{electron}} = \frac{\frac{h c}{E}}{\frac{h}{2 mE}} = c \frac{2 m}{E}$
