Sound Waves

Front

What are sound waves?

Back

Sound waves are vibrations that travel through a medium (solid, liquid, or gas) and can be heard when they reach a person's or animal's ear.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance through which sound waves can travel, such as air, water, or solid materials.

Front

How do sound waves travel through different mediums?

Back

Sound waves travel fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.

Front

What is frequency in relation to sound waves?

Back

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

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound; greater amplitude means a louder sound.

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 are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation, such as sound waves.

Front

What are transverse waves?

Back

Transverse waves are waves in which the particle displacement is perpendicular to the direction of wave propagation, such as light waves.

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 an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay, caused by sound waves bouncing off surfaces.
