Calculate de Broglie wavelength of an electron travelling at `1 %` of the speed of light.

Text Solution

Verified by Experts

According to de Brogie equation, ` lambda=(h)/(m upsilon)`
Mass of electron `=9.1 xx 10^(-31)kg`, Planck's constant `=6.626 xx 10^(-34)kg m^(2)s^(-1)`
Velocity of electron `=1%` of speed of light `=3.0 xx 10^(8)xx0.01=3.0 xx 10^(6)m s^(-1)`
Wavelength of electron `(lambda)=(h)/(m upsilon)=((6.626 xx 10^(-34)kg m^(2)s^(-1)))/((9.1 xx 10^(-31)kg ) xx (3xx10^(6) ms^(-1)))=2.43 x 10^(-10)m`.
