if the velocity of the electron in Bohr'...

if the velocity of the electron in Bohr's first orbit is `2.19xx10^(6)m*s^(-1)`, calculate the de Broglie wavelength associated with it.

Text Solution

Verified by Experts

`v=2.19xx10^(6)m*s^(-1),m=9.108xx10^(-31)kg`
`lamda=(h)/(mv)=(6.626xx10^(-34)kg*m^(2)*s^(-1))/((9.108xx10^(-31)kg)xx(2.19xx10^(6)m*s^(-1)))`
`=3.32xx10^(-10)m=332xx10^(-12)m=332`pm
