Question

An electron is associated with a wavelength of 10nm . calculated the velocity of electron

Answer 1

Answer:3 x 10^17

Explanation:given,

wavelength of electron energy wave,(lamda)=10nm

=10^{-9}.         [1nm=1x10^{-9}m]

velocit of light,c=3x10^{8}

velocity of electron=?

wee know,

v=c/lamda

v=(3x10^{8})/(10^{-9})

=3x10^{17}
