Calculate the wavelength of an electron ...

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

Text Solution

Verified by Experts

Velocity of an electron `(v)=2.05xx10^(7)m*s^(-1)`
According to de Broglie equation,
wavelength `(lamda)=(h)/(mv)`
`=(6.626xx10^(-34)J*s)/((9.108xx10^(-31)kg)xx(2.05xx10^(7)m*s^-1))`
`=3.549xx10^(-11)m`
Thus, wavelength of the electron will be `3.549xx10^(-11)`m.
