Waves and Energy
Waves, Light, Sound
Question | Answer |
---|---|
Light is what form of energy on the Electromagnetic Spectrum? | radiant |
All waves on the electromagnetic spectrum are called ___________________ waves. | transverse |
What color light is a reflection of all the colors on the visible spectrum? | white |
What color absorbs all colors of the visible spectrum? | black |
What do we call it when light bounces off an object? | reflection |
What do we call it when light waves are bent, as they move through a more dense medium? | refraction |
What do we call the top of the wave? | crest |
What do we call the resting position of a wave? | baseline |
What do we call the height of a wave (or amount of energy in a wave)? | amplitude |
What do we call the NUMBER OF WAVES that pass a point in one second? | frequency |
What do we call the distance from one wave to another (crest to crest or trough to trough)? | wavelenght |
How can you tell the difference between the different forms of energy on the EM spectrum? | different amounts of energy, different wavelengths, different frequencies |
How are sound waves transferred? | by particles bumping |
All sound is created when matter ________________. | vibrates |
Sound waves are called ______________ waves. | compression |
Does sound need a medium (matter) to transfer energy? | yes |
What state of matter transfers sound energy best? | solids because they are more dense |
What state of matter transfers sound energy least? | gases because they are the least dense |
Why does white light get bent into colors when the beam passes through a prism? | the prism is more dense so it slows the light waves down and they then bend |
Why can't you hear sound in space? | there is no matter to transfer sound |
