Radio station KRED in Eureka, California, broadcasts electromagnetic radiation at a frequency of 98.3 MHz (megahertz). What is the wavelength of these radio waves, expressed in meters?

Answer :

Final answer:

The wavelength of the radio waves is approximately 3.05 meters.

Explanation:

To calculate the wavelength of the radio waves, we can use the equation: wavelength = speed of light / frequency.

Given that the frequency of the radio waves is 98.3 MHz (megahertz), we need to convert it to hertz by multiplying it by 10^6. This gives us a frequency of 98.3 x 10^6 Hz.

Using the equation, we can substitute the values: wavelength = (3 x 10^8 m/s) / (98.3 x 10^6 Hz).

Simplifying the equation, we get: wavelength = 3.05 meters.

Therefore, the wavelength of these radio waves is approximately 3.05 meters.
