Write the relationship of de Broglie wavelength `lambda` associated with a particle of mass m in terms of its kinetic energy K.

Text Solution

Verified by Experts

Kinetic energy of the particle, `K=1/2 mv^2 =(p^2)/(2m)`
`p=sqrt(2mK)`
de-Broglie wavelength of the particle `lambda=h/p=h/(sqrt(2mK))`
