The kinetic energy of an electron is 4.5...

The kinetic energy of an electron is `4.55×10 ^ (−25)` J. Calculate the wavelength, (h=`6.6×10 ^ (−34)` Jsec,mass of electron=`9.1×10^ (−31)` kg).

Text Solution

Verified by Experts

`lamda = (h)/(sqrt(2m(KE))) = (6.626 xx 10^(-34)J.sec)/(sqrt(2 xx 9.1 xx 10^(-31)Kg xx 4.55 xx 10^(-25)J)) = 7.28 xx 10^(-7) m`
