What is the wavelength of an electron moving with a velocity of `2.0xx10^(7)"ms "^(-1)` ?

Text Solution

Verified by Experts

Formulae:
`lamda=(h)/(mv)`
`=(6.625xx10^(-34))/(9.1xx10^(-31)xx2xx10^(7))`
`=0.3640xx10^(-34)xx10^(+24)`
`=0.3640xx10^(10)m`
`=0.3640Å`
`h=6.625xx10^(-34)J.sec`
`m=9.1xx10^(-31)kg`.
`V=2.0xx10^(7)m//sec`.
