Question

The wavelength of the radio waves of an FM station is 3.10 meters. What is the frequency (s^-1) used by the FM station?

A) 97.4 s^-1
B) 3.10 s^-1
C) 10.3 s^-1
D) 0.323 s^-1

Answer 1

The frequency of the FM station is 97.4 s^-1.

Step-by-step explanation:

The wavelength of radio waves can be calculated using the formula:

Wavelength = speed of light / frequency

In this case, the wavelength of the radio waves is 3.10 meters. To find the frequency, we can rearrange the formula:

Frequency = speed of light / wavelength

Since the speed of light is approximately 3.00 x 10^8 meters per second, we can substitute the values:

Frequency = 3.00 x 10^8 m/s / 3.10 m = 9.68 x 10^7 s^-1

Therefore, the correct answer for the question is option A) 97.4 s^-1.
