Answer

Brief Explanations:

  1. Radio waves have the longest wavelength on the electromagnetic spectrum. This is a well - known fact in physics as they are used for long - distance communication and have wavelengths ranging from about 1 millimeter to 100 kilometers.
  2. Gamma rays have the shortest wavelength on the electromagnetic spectrum. They are produced by nuclear reactions and radioactive decay and have wavelengths less than 0.01 nanometers.
  3. The visible light spectrum, with wavelengths approximately between 380 - 700 nanometers, is what we can see. This is evident from the fact that our eyes are sensitive to this range of wavelengths and we perceive different colors within this range.

Answer:

  1. Radio waves. They are used for long - distance communication and have long wavelengths.
  2. Gamma rays. Produced by nuclear reactions and have very short wavelengths.
  3. Visible light with wavelengths approximately 380 - 700 nanometers. Our eyes are sensitive to this range.
