Front

Longitudinal Waves

Back

Particles in the medium move back and forth along the same direction that the wave travels.

Example of Mechanical Wave

Back

Front

Energy Transfer in Waves

Back

Waves transfer energy, not matter.

Front

Transverse Wavelength

Back

The distance between two consecutive crests or troughs in a wave.

Front

Compression

Back

The region in a longitudinal wave where particles are squeezed together

Front

Frequency and Sound

Back

Frequency is related to a sound’s pitch.

Front

Perception of low frequency

Back

A low frequency is perceived as a low-pitched note.

Front

Decreasing wavelength effect

Back

Decreasing the wavelength increases the frequency.

Front

Sound energy perception

Back

Ears detect variations in sound energy as pitch changes.

Front

Reflection

Back

When a wave hits a surface and bounces off.
