What are electromagnetic waves?

• sound waves
• electric & magnetic fields (energy) that travel through empty space very quickly
• Someone's name
• things like longitudinal waves

How are electromagnetic waves different from other waves? 

• They have very short wavelengths 
• They transmit energy instead of matter 
• They can travel through empty space
• They can change direction by reflection
