Gamma rays are emitted from nuclei of radioactive atoms. They are nothing
Correct answer: A. High-energy electromagnetic radiations
- A. High-energy electromagnetic radiations
- B. Electrons
- C. Protons
- D. Neutrons
Explanation
This is the correct answer. Gamma rays are a type of electromagnetic radiation, similar to visible light, X-rays, and radio waves. However, they have much higher energy and shorter wavelengths than these other types of radiation. Gamma rays are emitted from the nuclei of radioactive atoms as a result of nuclear decay processes, such as alpha decay or beta decay.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
