WYEP is a radio station in Pittsburgh, Pennsylvania, that airs on 91.3 FM. This means it broadcasts at a frequency of 91.3 megahertz, or 9.13 x 107 hertz. What is its wavelength? Make sure to show all your
work and the correct units.

Answer 1

To calculate the wavelength of a radio station's frequency, we can use the formula:

Wavelength = Speed of Light / Frequency

The speed of light is approximately 3 x 10^8 meters per second.

Given that the frequency of WYEP radio station is 9.13 x 10^7 hertz (91.3 megahertz), we can plug in the values:

Wavelength = (3 x 10^8 m/s) / (9.13 x 10^7 Hz)

Dividing the values, we get:

Wavelength = 3.28 meters

Therefore, the wavelength of WYEP radio station's frequency is approximately 3.28 meters.
