Sound waves

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) by vibrating particles.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

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

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of wave travel, while in longitudinal waves, the particle movement is parallel to the direction of wave travel.

Front

What is an example of a longitudinal wave?

Back

Sound waves are an example of longitudinal waves.

Front

What is an example of a transverse wave?

Back

Light waves and waves on a string are examples of transverse waves.

Front

How do you determine the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Wavelength x Frequency.

Front

What does frequency mean in relation to waves?

Back

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