Sound waves

The phases of matter sound can travel through (check all that apply)

• solid

• liquid

• gas

• space

The higher the pitch, the _____ the wavelength and the ____ the frequency.

• shorter, higher

• shorter, lower

• longer, higher

• longer, lower

A disturbance that travels through a medium as a longitudinal wave

• sound
• wavelength
• pitch
• frequency

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

The number of wavelengths that pass a point each second

• frequency
• wavelength
• pitch
• amplitude

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

A wave in which the vibration is in the same direction as that in which the wave is traveling; sound waves

• longitudinal wave
• ocean wave
• transverse wave
• mechanical wave

The part of a longitudinal wave where the particles of the medium are close together.

• rarefaction
• compression
• crest
• trough

A part in a longitudinal wave where the particles are spread apart

• compression
• rarefaction
• crest
• trough
