If the velocity of an electron in Bohr's...

If the velocity of an electron in Bohr's first orbit is `2.19xx10^(6) ms^(-1)`, what will be the de Broglie wavelength associated with it?

Text Solution

Verified by Experts

`lambda=h/(mv)=(6.626 xx 10^(-34))/((9.11 xx 10^(-31)) xx (2.19 x 10^(6))`
`=3.32 xx 10^(-10)m`
=332 pm
