Sound Wave Physics

A disturbance that travels through a medium as a longitudinal wave

• sound
• wavelength
• pitch
• frequency

NGSS.HS-PS4-1

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

• sound
• diffract
• pitch
• volume

Tags

NGSS.MS-PS4-2

travels through solids fastest because the molecules are closer together

• speed of sound
• wavelength
• frequency
• amplitude

Tags

NGSS.HS-PS4-1

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

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

• pitch
• frequency
• sound
• medium

When the sound source moves, the frequency changes
ex. police car siren sounding lower pitch after the car passes

• pitch
• frequency
• Doppler Effect
• medium

NGSS.HS-PS4-1

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

NGSS.HS-PS4-1

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
