Sound Waves

Front

Loudness

Back

Amplitude (height)
Higher amplitude = louder sound

Lower amplitude = quieter sound

Front

Pitch

Back

Frequency (# of waves)

High frequency = high pitch

Low frequency = low pitch

Front

Sound Wave Speed

Back

Depends on how close the particles are to each other.

Closer Particles = faster

Spread out particles = slower

Front

Solid

Back

particles close together

Front

Liquid

Back

Particles spread apart a small amount

Front

Gas

Back

Particles spread far apart

Front

Reflection

Back

sound wave hits an object and bounces off

Front

Transmission

Back

sound wave passes through a material

Front

Absorption

Back

Sound wave enters a material and stays there (transfers the energy into the material)

Front

Sound in Space

Back

Sound is not able to travel in space as there are no particles in space to bump into each other and pass the energy along
