What are three properties of electromagnetic waves?

Question

They travel slower than the speed of light, they include visible light waves, and they can transfer energy through empty space.
They need matter through which to travel, they travel at the speed of light, and they include visible light waves.
They travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.
They include ultraviolet waves, they need matter through which to travel, and they travel slower than the speed of light.

Answer 1

The correct statement about the properties of electromagnetic waves is: They travel at the speed of light, they include visible light waves, and they can transfer energy through empty space.

Here’s a breakdown of why this is correct:

1. They travel at the speed of light: Electromagnetic waves travel through a vacuum at approximately 299,792 kilometers per second (the speed of light).

2. They include visible light waves: The electromagnetic spectrum includes various types of waves, including infrared, visible light, ultraviolet, X-rays, and radio waves.

3. They can transfer energy through empty space: Electromagnetic waves can propagate through a vacuum, carrying energy without needing a medium (like air or water) to travel through.
