Calculate the frequency of revolution of...

Calculate the frequency of revolution of electron in the first Bohr orbit of hydrogen atom, if radius of first Bohr orbit is 0.5Å and velocity of electron in the first orbit is `2.24xx10^6m//s`.

Text Solution

Verified by Experts

Here, `v=?, r=0.5Å=0.5xx10^(-10)m`
`v=2.24xx10^6m//s`
`v=(2v)/(2pir)=(2.24xx10^6)/(2xx3.14xx0.5xx10^(-10))`
`7.13xx10^(15)Hz`
