Q. 94.3( 3 Votes )

Relativistic corr A. λ =10nm

B. λ =10–1nm

C. λ =10–4nm

D. λ =10–6nm

Answer :

We know the de Broglie wavelength is given by,

where h is the Planck’s constant, m is the mass and v is the velocity

(a) When, λ =10nm

(b) When, λ =10–1nm

(c) When, λ =10–4nm

(d) When, λ =10–6nm

Hence, in cases (c) and (d) velocities are greater than the speed of light and hence relativistic corrections will become important for an electron.
