(a) Compute the effect of collisional damping on the propagation of Langmuir waves (plasma oscillations), by adding a term -mnvv to the electron e-quation of motion and rederiving the dispersion relation for Te (b) Write an explicit expression for Im (w) and show that its sign indicates that the wave is damped in time.
