Waves that transfer electrical and magnetic energy are called?

• A. Transparent
• B. Electromagnetic waves
• C. Visible light
• D. Translucent

Answer: (B)

Waves that transfer electrical and magnetic energy are electromagnetic waves. These waves are made of swinging electric and magnetic fields that travel together through space. They don’t need a material medium to move, so they can propagate in vacuum as well as through air or other substances, all traveling at the speed of light in a vacuum. This broad category covers a wide range of waves from radio and microwaves to infrared, visible light, ultraviolet, X-rays, and gamma rays. They share the same basic mechanism of energy moving through changing electric and magnetic fields. The other terms describe materials’ properties, not the type of wave. Transparent means light passes through clearly, and translucent means light passes but is scattered. Visible light is just one portion of the electromagnetic spectrum, not the general name for all waves that carry electric and magnetic energy.
