Mechanical Waves Flashcard December 2024

Front

What is frequency?

Back

Frequency is the number of wavelengths that pass a point each second.

Front

What are mechanical waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through.

Front

What happens to sound when the amplitude increases?

Back

When the amplitude of a sound increases, the sound becomes louder.

Front

What is the relationship between amplitude and sound?

Back

Higher amplitude results in louder sound.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves move perpendicular to the direction of the wave, while longitudinal waves move parallel to the direction of the wave.

Front

What is a wavelength?

Back

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

Front

What is the period of a wave?

Back

The period is the time it takes for one complete wavelength to pass a point.

Front

How does frequency relate to pitch?

Back

Higher frequency results in a higher pitch of sound.

Front

What is energy in the context of waves?

Back

Energy in waves is related to the amplitude; higher amplitude means more energy.

Front

What is the speed of sound?

Back

The speed of sound is the distance sound travels in a given amount of time, which varies based on the medium.
