Wavelength (λ) = Speed of light (c) / Frequency (f)
The speed of light is approximately 299,792,458 meters per second (m/s). The frequency of the FM radio station 91.50 FM is 91.50 MHz, which is equivalent to 91,500,000 Hz.
Substituting the values into the formula, we get:
λ = (299,792,458 m/s) / (91,500,000 Hz)
λ ≈ 3.27 meters
Therefore, the wavelength of FM radio station 91.50 FM is approximately 3.27 meters.
