What are waves?

Back

Waves are disturbances that transfer energy from one place to another without transferring matter.

How do we hear sounds?

Back

We hear sounds when sound waves travel through the air and reach our ears, causing vibrations that our brain interprets as sound.

What is amplitude?

Back

Amplitude is the maximum displacement of a wave from its rest position, which determines the loudness of a sound.

What is frequency?

Back

Frequency is the number of waves that pass a point in a given amount of time, usually measured in Hertz (Hz).

What happens to sound waves as they travel through different materials?

Back

Sound waves travel at different speeds depending on the material; they travel fastest in solids and slowest in gases.

What happens when two waves meet?

Back

When two waves meet, they can interfere with each other, leading to constructive interference (amplitude increases) or destructive interference (amplitude decreases).

What is the relationship between amplitude and loudness?

Back

The greater the amplitude of a sound wave, the louder the sound will be.

What is the relationship between frequency and pitch?

Back

Higher frequency waves produce higher pitches, while lower frequency waves produce lower pitches.
