What does “EM” stand for? EM Spectrum for $100

Electromagnetic Back to Game

The small part of the EM spectrum we can see with just our eyes is called what? EM Spectrum for $200

Back to Game Visible Light

EM Spectrum for $300 Draw a high energy wave

Back to Game

EM Spectrum for $400 Name the colors of the visible spectrum in order from lowest to highest energy

Back to Game 1.Red 2.Orange 3. Yellow 4. Green 5. Blue 6. Indigo 7. Violet

Daily Double!! Draw a low energy wave and label the crest, trough and wavelength

Back to Game

Lenses for $100 When light passes through a lens it…..

Back to Game Bends / Refracts

Lenses for $200 Name the type of lens pictured below

Back to Game A Concave Lens

Lenses for $300 A convex lens makes things look……

Back to Game Bigger / Larger

Lenses for $400 Name the tool we used which is made of a convex lens

Back to Game Magnifying glass

Lenses for $500 Explain how a concave or convex lens causes refraction

Back to Game What is a vacuole Parallel light rays travel through a concave lens and bend outward Parallel light rays travel through a convex lens and bend inward OR

Reflection for $100 Reflection is when light …….

Back to Game Bounces

Reflection for $200 How are the angle of incidence and angle of reflection related?

Back to Game They are equal

Reflection for $300 If an angle of incidence is 45 degrees what is the angle of reflection?

Back to Game 45 degrees! 45

Reflection for $400 Draw a 30 degree angle bouncing off of a mirror using your protractor

Back to Game

Reflection for $500 Explain why objects appear to have color

Back to Game White visible light reacts with the surface of an object. Some colors are absorbed while others are reflected. The colors that are reflected give an object its color

Refraction for $100 Refraction is when light…..

Back to Game Bends

Refraction for $200 What are the two things that happen when light travels through a prism

Back to Game 1.Light changes speed 2.Light bends

Refraction for $300 Why does a pencil appear broken/bent in water?

Back to Game The light entering the water is refracted or bent so the object in the water also appears bent

Refraction for $400 Draw a light ray being refracted through a clear surface

Back to Game

Refraction for $500 Explain why white light creates a rainbow when it refracts

Back to Game White light is made of all of the colors of the rainbow mixed together. When the white light refracts, the colors separate out.

Absorption for $100 Absorption is when light…..

Back to Game Is taken in (sucked up)

Absorption for $200 What colors are being absorbed when a white light is shown at a red gummy bear?

Back to Game Orange, Yellow, Green, Blue, Indigo and Violet

Absorption for $300 Explain why nothing happens when we shine a green laser at a red gummy bear

Back to Game The green light is absorbed

Absorption for $400 Draw a diagram of a absorbed ray of light

Back to Game

Absorption for $500 Explain Transmission

Light passes right through an object Back to Game

How many points do you want to risk?

Describe the path that light takes through the eye

1.Cornea 2. Pupil 3. Lens 4. Vitreous Humor 5. Retina 6. Optic Nerve 7. Brain
