What are light waves?

However, in physics, 'light waves' often refer to any and all waves in the electromagnetic spectrum, and this is what we will discuss in this lesson. The Different Types of Light Waves Radio waves are at the red end of the electromagnetic spectrum. read more

Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation. read more

When a wave of light is transformed and absorbed as a photon, the energy of the wave instantly collapses to a single location, and this location is where the photon "arrives." This is what is called the wave function collapse. This dual wave-like and particle-like nature of light is known as the wave–particle duality. read more

Electromagnetic waves (or electromagnetic radiation) are waves made of oscillating magnetic and electric fields, and include radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. read more
