Question

Find the ratio of de broglie wavelength of proton and alpha particle of same energy

Answer 1

Your answer is here .

The ratio ofde broglie wavelength of proton and alpha particle of same energy is

Answer 2

Answer:

The ratio of de Broglie wavelength of proton and alpha particle of same energy is 2:1

Explanation:

De Broglie wavelength is given by the equation,

λ$=\frac{h}{p}$

Converting momentum in terms of kinetic energy and mass we get,

λ=$\frac{h}{\sqrt{2Em} }$

The ratio of De Broglie wavelength of proton and alpha particle can be given by

λproton/λalpha=√Μalpha/Mproton

Malpha=4Mproton

∴λproton/λalpha=√4=2

Therefore,  the ratio of de Broglie wavelength of proton and alpha particle of same energy is 2:1
