Sound and light waves

The medium is the substance through which sound waves travel, such as air, water, or solids.

Wavelength is the distance between one point on a compression and the corresponding point on the next compression in a sound wave.

As frequency increases, pitch also increases.

A compression is a region in a longitudinal wave where the particles are closest together.

A transverse wave occurs when the disturbance is at a right angle to the direction the wave is moving, such as heat and light waves.

A rarefaction is a region in a longitudinal wave where the particles are spread apart.

As frequency increases, wavelength decreases, and vice versa.

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

In a longitudinal wave, the particles of the medium move parallel to the direction of the wave, while in a transverse wave, they move perpendicular to the direction of the wave.

Amplitude is the maximum distance that the particles of a medium move from their rest position when a wave passes through.
