An electron is moving with an initial velocity and is in a magnetic field Then it’s de Broglie wavelength

 7

An electron (mass m) with an initial velocity is in an electric field . It’s de Broglie

wavelength at time t is given by


 9

Relativistic corrections become necessary when the expression for the kinetic energy becomes comparable with mc2, where m is the mass of the particle. At what de Broglie wavelength will relativistic corrections become important for an electron?

 10

Two particles A1 and A2 of masses m1, m2 (m1 > m2) have the same de Broglie wavelength. Then
