Question

A proton, a neutron, an electron and an &#945; -particle have same energy. If &#955; p , &#955; n , &#955; e and &#955; &#945; are the de Broglie's wavelengths of proton, neutron, electron and &#945; particle respectively, then choose the correct relation from the following

Quantrex Academy · Accepted Answer

Correct answer: B. &#955; a &#60; &#955; n &#60; &#955; p &#60; &#955; e

The de-Broglie wavelength &#955; &#160; = &#160; h 2 m ( K . E . ) where, h and K . E . are constant &#955; &#8733; 1 m m = Mass of the particle Thus, with increasing mass of particle de-Broglie wavelength decreases. Order of mass m e &#60; m p &#60; m n &#60; m &#945; Order of de-Broglie wavelength is &#955; a &#60; &#955; n &#60; &#955; p &#60; &#955; e

A proton, a neutron, an electron and an α -particle have same energy. If λ p , λ n , λ e and λ α are the de Broglie's wavelengths of proton, neutron, electron and α particle respectively, then choose the correct relation from the following
