Question 1

What are electromagnetic waves

Answer 1

Transverse waves that transfer energy from the source of the waves to an absorber

Question 2

What do electromagnetic waves form?

Answer 2

A continuous spectrum

Question 3

What else do electromagnetic waves have in common

Answer 3

All types of electromagnetic waves travel at the same velocity through a vacuum (space) or air

Question 4

Answer 4

In terms of their wavelength and their frequencies.

Question 5

What is the order of electromagnetic waves from long to short wavelength

Answer 5

Radio waves, microwaves, infrared, visible light (red to violet), ultraviolet, X-rays and gamma rays.

Question 6

What is the order of electromagnetic waves from low to high frequency?

Answer 6

Radio waves, microwaves, infrared, visible light (red to violet), ultraviolet, X-rays and gamma rays.
