The nature of light waves is similar to :

  • A.Cathode rays
  • B.Cosmic rays
  • C.Gamma rays
  • D.Alpha rays

Answer: C

Light waves are similar in nature to gamma rays.

Visible light and gamma rays are both electromagnetic waves: oscillating electric and magnetic fields travelling at the speed of light. They differ only in wavelength, gamma rays being at the short-wavelength, high-energy end of the spectrum.

Cathode rays are streams of electrons, alpha rays are helium nuclei, and cosmic rays are mostly high-energy protons and atomic nuclei. These are particles, not electromagnetic waves.
