Sample NEET Mock Test - Question 2

### An electron and a proton have the same wave length. Which one of the following statements is correct about them?

Detailed Solution for Sample NEET Mock Test - Question 2

de-Broglie wavelength          λ = h/p​                  where  p = h/√2mE​

∴    λ = h/√2mE​

⟹λ ∝ 1/√m​                             (∵ E = constant)

As   me ​< mp​

⟹  λp ​< λe

Thus proton has smaller wavelength.
