SUMMARY
The wavelength of a 106.5 MHz FM radio signal is calculated using the formula wavelength = v/f, where v is the speed of light in a vacuum (approximately 3.0 x 10^8 m/s) and f is the frequency (106.5 x 10^6 Hz). The correct calculation yields a wavelength of approximately 2.82 meters. It is essential to use the speed of light rather than the speed of sound, as radio signals are electromagnetic waves, not sound waves. This distinction is crucial for accurate wavelength determination.
