Question

[OPTIONAL BONUS] Problem 12-6 in the text. [Why the sky is blue] 11.5 12-6. (Why the sky is blue) As shown in Eq. (1235), the radiated power of a Hertzian dipole is proportional to or f,ie., strongly dependent on the frequency. Sunlight passing through the atmosphere stimulates small particles to oscillate as tiny dipoles with frequency f of the incident light. These small particles re-radiate as dipole antennas. When you look up in the sky, what you see is this re-radiated light. The current I(t) is related to the charge q(t) of an oscillating dipole by i(t)=dq radiated power is proportional to the fourth power of the frequency. The sunlight consists of a broad range of visible spectrum. Explain why the sky looks blue. (a) (b) The scattring of electromagnetic waves by small particles is known as Rayleigh scattering Show that the dt
