What is waves
100
a wave that moves the medium perpendicular (at a right angle) to the direction in which waves travel
What are Transverse waves
100
one complete cycle of a wave or oscillation: the reciprocal of the frequency
What is the Period?
100
bouncing back of an object or a wave when it hits a surface through which it cannot pass
What is reflection
100
the maximum height or depth of the crest or trough of a wave
What is Amplitude
200
how are waves formed
What is when matter vibrates?
200
moves the medium parallel to the direction
What is longitudinal
200
If the frequency is 10 Hz and the speed is 20 m/s, this is the wavelength.
What is 2 meters?
200
the bending of waves as they enter a new medium at an angle
What is refraction
200
the number of complete waves or vibrations that pass a given point in a certain amount of time
What is frequency
300
The speed of a wave with a wavelength of 10 meters and a frequency of 2 Hz
What is 20 m/s?
300
particles of the medium are close together
What is compression
300
When external vibrations match an object’s natural frequency
What is Resonance
300
sound waves move through this material the fastest
What is a solid?
300
wavelength x frequency= ? ? ?
What is Speed (velocity)
400
the material through which a wave travels
What is a medium?
400
particles of the medium are farther apart
What is rarefaction
400
how much sound energy reaches the ear
What is volume
400
the interaction between waves that meet
What is Interference
400
how high or low a sound is; determined by the frequency of the vibration
What is Pitch
500
a repeated back-and-forth or up-and-down motion
What are vibrations?
500
the highest and lowest parts of a wave
What are the crest & trough
500
a shock wave that consists of compressed sound waves created when something moves faster than the speed of sound

500
The speed of sound is greatest when the temperature is _________
What is warmer
500
the reflection of a sound wave against a solid surface (think of your voice)
What is Echo
