Sound Waves

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force, often resulting in a significant increase in amplitude.

Front

How can resonance break an object?

Back

Resonance can break an object by forcing it to vibrate at its natural frequency for a long time, which can lead to structural failure.

Front

What do sound waves need to travel through?

Back

Sound waves must travel through a medium, such as air, water, or solid materials.

Front

Can sound waves travel through space?

Back

No, sound waves cannot travel through space because there is no medium for them to move through.

Front

What happens when a tuning fork vibrates due to a piano note?

Back

This is an example of resonance, where the tuning fork vibrates at its natural frequency in response to the sound from the piano.

Front

What is the relationship between frequency and pitch in sound waves?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.

Front

What is a medium in the context of sound waves?

Back

A medium is any substance (solid, liquid, or gas) through which sound waves can travel.

Front

What is the difference between sound wave 1 and sound wave 4 in terms of frequency?

Back

Sound wave 4 has a higher frequency than sound wave 1, resulting in a higher pitch.

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 diffraction in relation to sound waves?

Back

Diffraction is the bending of sound waves around obstacles or through openings, allowing sound to spread out.
