The speed of a wave depends on ______ and _________.
Frequency and wavelength
Where can sound not travel
Through a vacuum
Intensity [or loudness] of a sound relates to what characteristic of a wave?
Amplitude
What causes the shattering of a glass?
Matching its natural frequency with sound
What can change the speed of sound?
It increases with temperature
What is the Doppler effect?
A change in pitch due to a moving sound source
What causes a sonic boom?
Going faster than the speed of sound
What property of the wave does pitch depend on?
The frequency
What is it called when waves bend around a corner or through a narrow opening?
Diffraction
What is it called when a wave bends while going from one medium to another?
Refraction
What is it called when a wave bounces back after striking an edge?
Reflection
What are the units used to measure intensity or loudness?
Decibels(dB)

Resonance
What is a wave that has the medium move perpendicular while the waves move forward?
Transverse wave
What is a wave that has the medium move in the same direction as the wave?
Longitudinal
