Question | Answer |
---|---|
The bouncing of light off a surface | reflection |
Energy related to the position of an object | Potential energy |
Allowing some light to pass through | Translucent |
Bending of light as it passes from one material to another | Refraction |
Allowing most light to pass through | Transparent |
Reflecting or absorbing light | Opaque |
The distance matter is displaced from its resting position to produce a wave | Amplitude |
Energy of motion | Kinetic Energy |
How is a wavelength measured? | Crest to crest |
Why does a red bead appear red? | It absorbs all the colors of the spectrum and reflects red back. |
The types of energy produced when fossil fuels are burned at a generating station | chemical, thermal and electrical |
What type of energy does a rolling ball have? | Kinetic energy |
What type of energy does a stretched rubber band have? | Potential energy |
Why does a black asphalt driveway get hotter than a concrete driveway on the same hot day? | It absorbs all wavelegnths of light |
How does light travel? | In a straight line |
When observing the bottom of a fish tank with a flashlight, at what point is the light traveling fastest? | At the point right before it comes in contact with the water. |
Using the same fishtank and flashlight, when does the bending of light(refraction) occur? | At the point the light meets the water. That is why it is difficult to catch a fish when looking into water, the light causes the fish to appear in one spot but actually it is in another. |
How does high frequency affect the pitch of a sound wave? | It makes it higher |
