The electromagnetic spectrum stretches from gamma rays up to which waves?
ALong ripple waves
BLong rolling waves
CLong rising waves
DLong radio waves
Answer & Solution
Correct answer: D. Long radio waves
1. The spectrum is ordered by wavelength.
2. Gamma rays sit at the very short end.
3. The broad spectrum stretches from gamma rays to long radio waves.
4. So the far end is long radio waves.
