Electrons are accelerated through a potential difference of `150V`. Calculate the de broglie wavelength.

Text Solution

Verified by Experts

The correct Answer is:
1
`V=150V,h=6.62xx10^(-34)js,`
`m=9.1xx10^(-31)kg, " " e=1.6xx10^(-19)C`
`therefore=(h)/(sqrt(2Vem))=(6.62x10^(-34))/(sqrt(2xx9.1xx10^(-31)xx1.6xx10^(-19)xx150))=1overset(0)A`
