(a) The sun emits an electromagnetic wave to Earth surface. If the strength of electric field at certain point is 0.868 kV/m then find the magnetic field there. (b) Blue light has a wavelength of 470 nm. Find its frequency. (c) When you are tuned to a radio station that is 161 km away then how long does it take for an EM signal from the station to reach you? (d) EM waves are transverse in nature. What does this sentence mean?
