Final answer:
To find the wavelength of an FM radio wave with a frequency of 124.0 MHz, use the formula λ = c / ν. With the speed of light c being 3.00 × 10^8 m/s, the wavelength calculates to approximately 2.419 meters, making the closest answer 2.41 meters.
Step-by-step explanation:
The question asks to determine the wavelength in meters of an FM radio wave with a frequency (ν) of 124.0 MHz. To calculate the wavelength (λ), we use the formula λ = c / ν, where c is the speed of light in a vacuum, which is approximately 3.00 × 108 m/s. Plugging in the given frequency, we have:
λ = (3.00 × 108 m/s) / (124.0 × 106 Hz) = (3.00 × 108) / (124.0 × 106) meters = 2.41935483871 meters
Therefore, the closest answer to the given choices is b. 2.41 m.
