Suppose a popular FM radio station broadcasts radio waves with a frequency of 108. MHz. Calculate the wavelength of these radio waves. Round your answer to 3 significant digits.

The wavelength is

Explanation:

Radio waves are part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of 3.00x10^{8}m/s in vacuum.

Therefore, the wavelength can be determined by the following equation:

 (1)

Where c is the speed of light, is the wavelength and is the frequency.  

Then, can be isolated from equation 1

  (2)

Notice that it is necessary to express the frequency in units of Hz.  

⇒

But

Hence, the wavelength is

what type of charge does it have? negative

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
