The wavelength associated with an electron moving with a velocity of `10^10 cm per sec`.

Text Solution

Verified by Experts

Mass of the electron `=9.10xx10^(-28)g`
velocity of electron`=10^(10)` cm per sec.
`h=6.62xx10^(-27)erg-sec`
`h=6.62xx10^(27)erg-sec`
According to de Broglie equation,
`lamda=(h)/(mv)=(6.62xx10^(-27))/(9.10xx10^(-28)xx10^(10))`
`=7.72xx10^(-10)cm`
`=0.0772` Ã…
