Final answer:
Radiations including radio, light, and gamma waves are part of the electromagnetic spectrum, traveling at the speed of light and propagated by interacting electric and magnetic fields. They have differing wavelengths and energy, where shorter wavelengths correlate with higher energies and frequencies. Gamma rays are an example of high-energy electromagnetic radiation with very short wavelengths.
Step-by-step explanation:
Radiations such as radio, light, and gamma waves are all examples of electromagnetic radiation. Electromagnetic radiations are waves that are propagated through a space by the interaction of electric and magnetic fields. These waves, which form the electromagnetic spectrum, include a wide range of types, from radio waves on the one end to gamma rays on the other, with varying wavelengths and energy levels. The shorter the wavelength, the higher the frequency and the more energy the wave carries.
The behaviors of these waves, such as propagation, reflection, refraction, and interaction with matter, follow the laws of physics. Electromagnetic radiation travels at a constant speed, known as the speed of light, which is approximately 300 million meters per second in a vacuum. The energy flux, which is the amount of energy passing through a unit area per second, is measured in watts per square meter.
The differences in energy levels within atoms or ions lead to the emission of electromagnetic radiation of various frequencies, which is observed in the emission spectrum. High-energy radiation such as gamma rays, produced by nuclear interactions, have much shorter wavelengths compared to radio waves, which result from atomic interactions and include lower energy levels.
