Question

The wavelength of a photon and the deBroglie wavelength of an electron and uranium atom are identical. Which one of them will have highest kinetic energy 1) Photon 2) Electron 3) U – atom 4) nothing can be predicted

Answer 1

Explanation:

here lembda is constant and Planck's Constant is also a constant so I am removing them and solving with the remaining terms kinetic energy and mass
