ARadio waves
BMicrowaves
CInfrared
DGamma rays
Answer & Solution
Correct answer: D. Gamma rays
1. The spectrum runs from very long waves to very short ones.
2. Radiation with the shortest wavelengths, no longer than 0.01 nanometer, is gamma rays.
3. Radio waves sit at the opposite end, with the longest waves of the family.
