Calculate the wavelength of the de Brogl...

Calculate the wavelength of the de Broglie wave associated with an electron moving with a velocity of `2.05xx10^(7)m*s^(-1)`.

Text Solution

Verified by Experts

From de Broglie equation: `lamda=(h)/(mv)` [where, `lamda`=wavelength, m=mass of the electron, v=velocity of the electron], `lamda=(6.626xx10^(-34))/((9.11xx10^(-31))xx(2.05xx10^(7)))=3.548xx10^(-11)`m
