Relativistic corrections become necessary when the expression for the kinetic energy \( \frac{1}{2} m v^{2} \), becomes
- comparable with \( m c^{2} \), where \( m \) is the mass of the
- electron. At what de-Broglie wavelength, will relativistic
- corrections become important for an electron?
- (a) \( \lambda=10 \mathrm{~nm} \)
-(b) \( \lambda=10^{-1} \mathrm{~nm} \)
(c) \( \lambda=10^{-4} \mathrm{~nm} \)
(d) \( \lambda=10^{-6} \mathrm{~nm} \)
