What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is a mechanical wave?

Back

A mechanical wave requires a medium (solid, liquid, or gas) to travel through.

What is frequency?

Back

Frequency is the measure of how many waves pass a point in a certain amount of time, usually measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs of a wave.

Front

What is amplitude?

Back

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

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

What is sound?

Back

Sound is a form of energy that travels in waves and is produced by vibrating objects.

Front

How does sound travel through different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.
