A proton and an electron have same kinetic energy. Which one has greater de Broglie wavelength. Justify.

Text Solution

Verified by Experts

de-Broglie wavelength of the particle is `gamma =h/p=h/(sqrt(2mk))
i।egamma prop1/(sqrt(m))`
As `m_eltltm-p,gamma_egtgtgamma_p`
Hence protons have greater de-Broglie wavelength
