WebThe electromagnetic spectrum is a fundamental aspect of physics and is closely related to fields such as optics, electromagnetism, and quantum mechanics. Understanding the electromagnetic spectrum is essential for understanding how light behaves and how it can be used in a variety of applications. →Why is studying the electromagnetic spectrum ... WebTransverse waves that transfer energy from the source of the waves to an absorber. All electromagnetic waves share the following properties: They are all transverse. They can all travel through a vacuum. They all travel at the same speed in a vacuum. There are 7 types of electromagnetic waves, which all together form a continuous spectrum.
