Bending of waves around an object (such as through a doorway)

• sound
• diffract
• pitch
• volume

travels through solids fastest because the molecules are closer together

• speed of sound
• wavelength
• frequency
• amplitude

How high or low a sound is; depends on the frequency (greater frequency= higher pitch)

• pitch
• frequency
• sound
• medium

The number of wavelengths that pass a point each second

• crest
• amplitude
• frequency
• pitch

If you want to change the pitch of a sound, you have to change the ___

• frequency
• amplitude
• speed
• volume

This is the unit used to measure the volume of a sound. 

• Decibel
• Medium
• Vibration
• Oscilloscope

This is what you get when sound waves are reflected, or bounce back, off of a hard surface.

• Amplitude
• Pitch
• Volume
• Echo
