Calculate wavelength (in nm) associated ...

Calculate wavelength (in nm) associated with a beam of protons moving with velocity of `10^(3)m*s^(-1)`. [Mass of proton `1.67xx10^(-27)kg,h=6.63xx10^(-34)J*s`]

Text Solution

Verified by Experts

de Broglie wavelength, `lamda=(h)/(mv)`
`=(6.63xx10^(-34))/(1.67xx10^(-27)xx10^(3))m=0.40xx10^(-9)m=0.40nm`
