Calculate the ratio between the wavelength of an electron and a proton, if the proton is moving at half the velocity of the electron (mass of the proton `=1.67xx10^(-27)kg`, mass of the electron`=9.11xx10^(-2)m`.

Answer

`9.2455xx10^(-2)m`

Explanation

Apply de Broglie equation `lamda=(h)/(mv)`
Wavelength of electron `=(6.625xx10^(-34))/(9.11xx10^(-31)v)`
Wavelength of proton `=(6.625xx10^(-34))/(1.67xx10^(-27)xx0.5v)`
