Explanation:
1) am radio waves
The lowest and highest frequencies of the radio signals are:
The speed of the waves is the speed of light,
, so to find the corresponding wavelengths we can use the basic relationship between frequency, wavelength and speed of a wave:
where f is the frequency and
the wavelength.
The wavelength corresponding to the lowest frequency is:
while the wavelength corresponding to the highest frequency is
So, the range of wavelengths is [187.5-545] m.
2) fm radio waves
This time, the lowest and highest frequencies of the radio waves are:
So the corresponding wavelengths are:
Therefore, the range of wavelengths of the rm radio signals is [2.8-3.4] m.
Speed only has force while the others have direction
