Light, radiation, and waves are interconnected concepts within the framework of the electromagnetic spectrum. Light refers specifically to the visible portion of the electromagnetic spectrum, which is the range of wavelengths that can be detected by the human eye. Radiation is a broader term that encompasses all types of energy emitted in the form of waves, including both light and other forms of electromagnetic radiation such as radio waves, microwaves, and X-rays. Waves refer to the oscillatory nature of electromagnetic radiation, propagating energy through space without the need for a medium. The electromagnetic spectrum is the complete range of all these electromagnetic waves, categorized into non-ionizing radiation (such as radio waves and visible light, which do not carry enough energy to ionize atoms) and ionizing radiation (such as X-rays and gamma rays, which have enough energy to remove tightly bound electrons from atoms).
In 3-5 sentences, explain how the terms light, radiation, and waves relate to one another?
