Here's how to calculate the wavelength of radio waves:

Understanding the Relationship

The speed of light (or any electromagnetic radiation) in a vacuum is denoted by 'c' and is related to frequency (f) and wavelength (λ) by the following equation:

c = fλ

Solving for Wavelength

1. Convert MHz to Hz: 81.6 MHz = 81.6 x 10^6 Hz

2. Rearrange the equation: λ = c / f

3. Substitute the values: λ = (3.00 x 10^8 m/s) / (81.6 x 10^6 Hz)

4. Calculate: λ ≈ 3.68 meters

Therefore, the wavelength of radio waves emitted at 81.6 MHz is approximately 3.68 meters.
