How do electromagnetic waves differ from mechanical waves?

Back

Electromagnetic waves can travel through empty space, while mechanical waves require a medium to travel.

Front

What is the order of the electromagnetic spectrum based on?

Back

The electromagnetic spectrum is ordered by increasing frequency.

Front

What is the relationship between wavelength and frequency?

Back

A wave with a large wavelength will have a low frequency and low energy.
