NGSS.HS-PS4-1

How much of the electromagnetic spectrum is visible?

• All of it

• None of it

• Most of it

• Only a small part

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
