Correct answer: Long wavelengths and low frequencies.
Explanation: Radio waves occupy the low‑frequency, long‑wavelength end of the electromagnetic spectrum. Their frequency range is commonly taken as about 3 kHz to 300 GHz, which corresponds (via λ = c/f, c ≈ 3×10^8 m/s) to wavelengths of roughly 100 km down to 1 mm. Examples: AM radio ~0.5–1.7 MHz (wavelengths of hundreds of meters), FM radio ~88–108 MHz (wavelengths ~3 m), and microwave links/satellites at GHz frequencies (wavelengths of centimetres).
