Sound Waves

Front

What type of energy does a sound wave have?

Back

Mechanical energy is the energy associated with the motion and position of an object. Sound waves are mechanical waves that require a medium (solid, liquid, or gas) to travel.

What two factors affect the speed of sound?

Back

The speed of sound depends on the type of medium (solid, liquid, gas) and the temperature of that medium. Sound travels faster in solids than in liquids and gases.

What is the distance from the beginning of one compression to the beginning of the next compression called?

Back

Wavelength is the distance between successive compressions or rarefactions in a wave.

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to the influence of external vibrations, leading to an increase in amplitude.

What are ultrasonic waves?

Back

Ultrasonic waves are sound waves that have a frequency higher than the upper limit of human hearing, typically above 20,000 Hz.

What are infrasonic waves?

Back

Infrasonic waves are sound waves with frequencies below the lower limit of human hearing, typically below 20 Hz.

What is the relationship between frequency and pitch?

Back

Frequency is the number of waves that pass a point in one second, and pitch is how high or low a sound seems to a listener. Higher frequency means higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, which determines the loudness of the sound.

What is the medium in which sound travels?

Back

The medium is the substance (solid, liquid, or gas) through which sound waves propagate.

What is the difference between compression and rarefaction?

Back

Compression is the region in a longitudinal wave where particles are closest together, while rarefaction is the region where particles are spread apart.
