Concept explainers
To explain: The FM antenna design which would be more sensitive to stations near 88
Explanation of Solution
Introduction:
There is a sinusoidal graph displaying the
An Electromagnetic wave travels at the
Here,
From equation (1), it can be observed that the frequency is inversely proportional to the wavelength. For all types of electromagnetic waves, the greater the frequency, the smaller will be the wavelength.
Thus, in order to be sensitive to stations near 88 MHz would require a longer wavelength antenna and for stations near 108 MHz, would require shorter wavelength antenna.
Conclusion:
Hence, it can be concluded that for 88 MHz station longer antenna design would be sensitive and for 108 MHz, shorter antenna design would be sensitive.
