Waves and Energy

Waves, Light, Sound

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
