Question

A local AM radio station broadcasts at a frequency of 697 kHz.Calculate the wavelength at which they are broadcasting.Wavelength = ( ??? )m(1 kHz = 103 sec -1)

Answer 1

The wavelength at which the AM radio station is broadcasting is approximately 430.46 meters.

Step-by-step explanation:

To calculate the wavelength of a radio wave, we can use the formula:

Wavelength = Speed of Light / Frequency

Given that the frequency of the AM radio station is 697 kHz, we first need to convert it to Hz by multiplying it by 10^3:

Frequency = 697 kHz * 10^3 = 697,000 Hz

Next, we can use the speed of light, which is approximately 3 x 10^8 m/s:

Wavelength = 3 x 10^8 m/s / 697,000 Hz = 430.46 meters

Therefore, the wavelength at which the AM radio station is broadcasting is approximately 430.46 meters.
