Why do we see objects as white?

• They absorb all light
• They reflect all light
• They absorb some light and reflect some light

How does all light travel?

• in sources
• in waves
• in groups
• in gases

True or false: as you move along the spectrum, left to right, the wavelengths decrease in size (get smaller)

• true
• false

Select the correct order of waves on the EMS 

• Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma
• Gamma, X-ray, Ultra, Vis, Infra, Micro, Radio
• Vis, Micro, Infra, Ultra, X-ray, Gamma, Radio
• Micro, Radio, Vis, Infra, Ultra, X-ray, Gamma

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays
