Question

KORA has a broadcast frequency of 98.3 MHz (1.0 MHz = 1.0 × 10⁶ Hz). Calculate the wavelength (in meters) of these FM radio waves.

Answer 1

To calculate the wavelength of FM radio waves, you can use the formula:
wavelength (m) = speed of light (m/s) / frequency (MHz). In this case, the wavelength of radio waves with a frequency of 98.3 MHz is approximately 3.05 meters.

Step-by-step explanation:

To calculate the wavelength of FM radio waves, you can use the formula:

wavelength (m) = speed of light (m/s) / frequency (MHz)

First, convert the frequency from MHz to Hz. In this case, 98.3 MHz becomes 98.3 × 106 Hz. The speed of light is approximately 3 × 108 m/s. Plugging these values into the formula gives:

wavelength (m) = 3 × 108 m/s / (98.3 × 106 Hz)

Calculating this gives a wavelength of approximately 3.05 meters.
