Explain how energy is transferred by radiation. State whether particles are required for this method of energy transfer

Answer 1

Energy transfer by radiation occurs through the emission of electromagnetic waves or photons. These waves travel through space and matter and transfer energy from one object to another. No particles are required for this method of energy transfer. Radiation can occur in the form of visible light, ultraviolet radiation, X-rays, and gamma rays, all of which have different wavelengths, frequencies, and energies. Some examples of energy transfer through radiation include the sun's rays heating up the Earth's surface, microwaves cooking food, and medical imaging techniques using X-rays.
