Sound Waves Flashcard

Front

What is a sound wave?

Back

A sound wave is a type of longitudinal wave that is created by vibrating objects and travels through a medium (like air, water, or solids) by compressing and rarefying the particles in that medium.

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations that are perpendicular to the direction of wave travel (like light waves), while longitudinal waves have oscillations that are parallel to the direction of wave travel (like sound waves).

What is wavelength?

Back

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

Front

How does amplitude affect sound?

Back

The amplitude of a sound wave determines its loudness; a larger amplitude means a louder sound, while a smaller amplitude means a quieter sound.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch of sound.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is the speed of sound?

Back

The speed of sound is the distance that sound waves travel in a given amount of time, typically around 343 meters per second in air at room temperature.

Front

What is compression in a sound wave?

Back

Compression is the region in a longitudinal wave where particles are close together, resulting in higher pressure.

Front

What is rarefaction in a sound wave?

Back

Rarefaction is the region in a longitudinal wave where particles are spread apart, resulting in lower pressure.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature because warmer temperatures cause particles to move faster, facilitating quicker wave propagation.
