Which of the following has the lowest frequencies?

Explanation:
The concept being tested is that electromagnetic waves cover a spectrum with frequencies ranging from very low to very high, and frequency is inversely related to wavelength (f = c/λ). That means waves with long wavelengths have low frequencies, and those with short wavelengths have high frequencies. Radio waves sit at the low-frequency end of the spectrum, with long wavelengths and relatively small frequencies, while gamma rays, X-rays, and ultraviolet have progressively higher frequencies (shorter wavelengths). So among the given options, radio waves have the lowest frequency.
