Question
What are electromagnetic waves? Describe a visible part of the spectrum.
Answer
Electromagnetic waves are a type of energy that travels through space. They are made up of both electric and magnetic fields that oscillate, or vibrate, in a synchronized manner. These waves don’t need any material medium to travel through; they can move through a vacuum, like outer space.
Visible Light: This is the part of the electromagnetic spectrum that our eyes can detect. It includes all the colours we see in a rainbow—red, orange, yellow, green, blue, indigo, and violet. Each colour corresponds to a different wavelength of light. Red has the longest wavelength, while violet has the shortest.
