Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is the relationship between frequency and period?

Back

Frequency and period are inversely related; frequency is the inverse of the period (Frequency = 1/Period).

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What are compressions in a longitudinal wave?

Back

Compressions are regions in a longitudinal wave where particles are close together.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are regions in a longitudinal wave where particles are spread apart.

Front

What happens to sound when amplitude increases?

Back

Increasing the amplitude of a sound wave makes the sound louder.
