EMS

How much of the electromagnetic spectrum is visible?

• All of it.
• None of it.
• Most of it.
• Very little of it.

What part of the electromagnetic spectrum can we see?

• Gamma Rays
• Visible Light
• Ultra Violet 
• Microwaves

Where does most our electromagnetic radiation come from?

• The sun.
• Cell phone towers.
• Inside the earth.
• Light bulbs.

Which correctly explains the relationship between the energy and frequency of a wave.

• High frequency = High Energy
• Low Frequency = High Energy
• High Frequency = Low Energy
• There is no relationship.

Which is NOT an example of electromagnetic radiation.

• A microwave being used to heat up pot roast.
• A dolphin communicating with a fellow dolphin using sonar.
• A remote using infrared radiation to change the channel.
• An x-ray machine being used to take a picture of a broken bone.

Which statement is true?
