Question

The wavelength \(λ\) of a photon and the de-Broglie wavelength of an electron have the same value. Find the ratio of energy of photon to the kinetic energy of electron in terms of mass \(m\), speed of light \(c\) and planck constant.

• A. \(\frac {λmc}{h}\)
• B. \(\frac {hmc}{λ}\)
• C. \(\frac {2hmc}{λ}\)
• D. \(\frac {2λmc}{h}\)

Answer 1

The Correct Option is D

The correct option is (D): \(\frac {2λmc}{h}\).
