The AM station KBOR plays your favorite music from the 20's and 30's at 1290 kHz. Find the wavelength of these waves.

Question

Quizplus · Accepted Answer

The formula to find the wavelength is: wavelength = speed of light / frequency

We know the frequency is 1290 kHz or 1290,000 Hz (since 1 kHz = 1000 Hz).

The speed of light is approximately 3 x 10^8 m/s.

Using the formula, we get:

wavelength = (3 x 10^8 m/s) / (1290,000 Hz) 
wavelength = 232.56 m

Therefore, the wavelength of the waves playing on KBOR is approximately 232 m, which is closest to choice D.
