Question
The mast on the sky tower is used to broadcast radio waves of different frequencies. The above diagram shows the wave crests of the two different radio signals.(i) Explain which of the two signals (A or B) are in the microwave range of frequencies and which is in the broadcast range of a normal radio station.
(ii) Which of the two signals would be more likely to be picked up by a radio receiver on a yacht anchored behind Rangitoto and why? The mast on the sky tower is used to broadcast radio waves of different frequencies. The above diagram shows the wave crests of the two different radio signals.

Explanation / Answer
(i) the above dig: ----------------------------------------------------------------------------------------- shows that, the wavecrests of the two diffrent frequencies of a radio signlas. as we know that, the wavelength of signal is inversly propotional to frequency. more over ,the wave length of a signal is depending on the distance between the crests of a signals. from the fig: it is obivious that, the wave length of signal B is less , the wave length of signal A is more. (because,the distances between the crests of A is more and B is less) so, the signal "B" is in the "microwave region" (because it is shorter range wavelength) thus, signal" A "is the "brodcoasting range" signal. ------------------------------------------------------------------------------------------------- (ii) the" signal A" is more lickely to picked up by the radio reciever due to" larger range of its wavelength"
