An electromagnetic wave of free space wavelength 0.5 mm propagates through a piece of indium antimonide that is placed in an axial magnetic field. There is resonant absorption of the electromagnetic wave at a magnetic field, B= 0.323 wb m ^-2 .

(i) What is the effective mass of the particle in question?

(ii) Assume that the collision time is 15 times longer (true for electrons around liquid nitrogen temperatures) than in germanium in the previous example. Calculate the mobility.

(iii) Is the resonance sharp? What is your criterion?
