AM waves have a wavelength of approximately 100 meters. FM waves have a wavelength of approximately 1 meter. Which one has a higher frequency? Which one has higher energy?

Sagot :

Answer:

We will see that AM wavelengths are, in average, 100 times larger than FM wavelengths, so the correct option is the third one.

How to find the ratio between the wavelengths?

First, we need to find the wavelengths.

For AM waves, the average is: 360m  (the range is from 170m to 550m)

For FM waves, the range is:  3.1m        (the range is from 2.78m to 3.41m)

Then the ratio is given by the quotient between these two:

360m/3.1m = 116

This means that AM waves have a wavelength around 100 times larger than FM waves, so the ratio of AM wavelength to FM wavelength is:

100 to 1.

Or, written like in the options:

10^2 to 1.

So the correct option is the third one.
