Electromagnetic Spectrum Lesson

How are electromagnetic waves different from other waves? 

• They have very short wavelengths 

• They transmit energy instead of matter 

• They can travel through a vacuum 

• They can change direction by reflection 

Which wave has a low frequency, a long wavelength, and low energy?

• A

• B

• Not enough information to determine

How much of the electromagnetic spectrum is visible?

• All of it

• None of it

• Most of it

• Only a small part

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern
