Amplitude
answer
The maximum distance that the particles of a wave's medium vibrate from their rest position
question
Wavelength
answer
The distance from any poiont on a wave to an identical point on the next wave
question
Frequency
answer
The number of waves produced in a given amount of time.
question
Reflection
answer
The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
question
Echo
answer
Reflected sound wave
question
Transmission
answer
Waves passing through an object
question
Refraction
answer
The bending of a wave as the wave passes between two substances in which the speed of the wave differs
question
Diffraction
answer
A change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
question
Interference
answer
The combination of two or more waves that results in a single wave
question
Constructive Interference
answer
Occurs when the crests of one wave overlaps the crests of another wave. The troughs also overlap. This results in a wave with a higher crest and a lower trough.
question
Destructive Interference
answer
Occurs when the crests of one wave and the troughs of another wave overlap. This results in a smaller amplitude or no wave at all.
question
Standing Wave
answer
A pattern of vibration that simulates a wave that is standing still
question
Resonance
answer
A phenomenon that occurs when two objects naturally vibrate at the same frequency; the sound produced by one object causes the other object to vibrate.
