Understanding Light Waves

Our eyes are sensitive to only a very small portion of the electromagnetic spectrum. What is that spectrum called?

• Infrared light
• Visible light
• Ultraviolet light
• X-ray light

Violet light has the _______wave of light that we can see.

• slowest
• longest
• weakest
• shortest

Green light has a wavelength range of how many nanometers?

• 400-450nm

• 492-577 nm

• 200-300 nm

• 600-650 nm

The colors of light that we can see are the same as a what?

• Rainbow

• Unicorn

• Super Nova

Light is also known as this type of energy what is it?

• Thermal energy
• Electromagnetic energy
• Nuclear energy
• Chemical energy

The light wave that is not visible to us that has the shortest wavelength?

• X-ray
• Ultraviolet ray
• Gamma ray
• Infrared ray

The light wave not visible to us that has the longest wavelength?

• X-ray wave
• Ultraviolet wave
• Infrared wave
• Gamma wave

The electromagnetic wave that has the longest wavelength is what?

• Long radio wave

• Microwave

• X-ray wave
• Short radio wave

This refers to the bending of visible light waves as they pass through matter.

• Absorption
• Diffraction
