Sound Waves

Front

What is the medium in the context of sound waves?

Back

The medium is the material (matter) through which a wave travels.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the Doppler Effect?

Back

The Doppler Effect is where the apparent wavelength of a wave is shifted due to the source moving.

Front

What frequency would you hear as a low pitched sound?

Back

A sound wave with a frequency of 50 Hz.

Front

What causes the change in pitch of a sound as the source moves towards or away from an observer?

Back

The change in pitch is due to a change in the sound wave's frequency.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitches, while lower frequency sound waves produce lower pitches.

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium, and it relates to the loudness of the sound.

Front

How does sound travel through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases due to the density and elasticity of the medium.

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.

Front

What is the relationship between sound intensity and loudness?

Back

Sound intensity is the power per unit area carried by a sound wave, and it is directly related to the perceived loudness of the sound.
