A vertical transmitter aerial emits a vertically polarised electromagnetic wave which travels towards a vertical receiver aerial. The wavelength of the wave is 0.80 m0.80\text{ m}0.80 m.
Calculate the frequency fff of the transmitted wave.
The electromagnetic wave is caused by electrons oscillating in the transmitter aerial. Each electron oscillates with simple harmonic motion. Calculate the maximum acceleration amaxa_{\text{max}}amax of an electron which oscillates with an amplitude of 2.5×10−6 m2.5 \times 10^{-6}\text{ m}2.5×10−6 m.
