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

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

Front

What is amplitude in a wave?

Back

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

Front

What is 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

How does temperature affect the speed of sound?

Back

As temperature increases, the energy of particle vibrations increases, which increases the speed of sound.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What is the relationship between frequency and wavelength?

Back

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

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, like sound waves.

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, like light waves.

Front

What is the speed of sound in air at room temperature?

Back

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