Calculate the wavelength of an electron ...

Calculate the wavelength of an electron moving with a velocity of `2.5xx10^(-7) ms^(-1)h=6.626xx10^(-34)Js:`mass of an electron=`9.11xx10^(-31)` kg.

Text Solution

Verified by Experts

`lamda=h/(mv)=(6.626xx10^(-34)Js)/(9.11xx10^(-31)Kgxx2.5xx10^(7)ms^(-1))=2.9093xx10^(-12)m.`
