For the Schumann resonances of Section 8.9 calculate the Q values on the assumption that the earth

Question:

For the Schumann resonances of Section 8.9 calculate the Q values on the assumption that the earth has a conductivity σ_e and the ionosphere has a conductivity σ_i, with corresponding skin depths 8_e and δ_i.

(a) Show that to lowest order in h/a the Q value is given by Q = Nh/(δ_e + δ_i) and determine the numerical factor N for all.

(b) For the lowest Schumann resonance evaluate the Q value assuming σ_e = 0.1 (Ωm)^–1, σ_i = 10^–5 (Ωm)^–1, h = 10² km.
