Question

A photon and an electron have an equal energy ' \(\text{E}\) '. The ratio of wavelength ' \(\lambda_\text{p}\) ' of photon to that of electron ' \(\lambda_\text{e}\) ' is proportional to

• A. \(\sqrt{\text{E}}\)
• B. \(\frac{1}{\sqrt{\text{E}}}\)
• C. \(\frac{1}{\text{E}}\)
• D. \(\text{E}\)

Hint:

Photon: $\lambda \propto \frac{1}{E}$ Electron: $\lambda \propto \frac{1}{\sqrt{E}}$

Answer 1

The Correct Option is A
