Properties of Sound Waves

Front

What is resonance?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to external vibrations matching that frequency.

Front

What is a medium in the context of sound waves?

Back

A medium is the material through which sound waves travel, such as air, water, or solids.

Front

What type of wave are sound waves classified as?

Back

Sound waves are classified as longitudinal waves.

Front

What do sound waves require to travel?

Back

Sound waves require a medium to travel through; they cannot travel through a vacuum.

Front

What happens during resonance?

Back

During resonance, vibrations traveling through an object match the object's natural frequency, causing it to vibrate more intensely.

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 difference between reflection and refraction of sound waves?

Back

Reflection is when sound waves bounce off a surface, while refraction is the bending of sound waves as they pass from one medium to another.

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.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature because warmer air has more energy, allowing sound waves to travel faster.

Front

What is the relationship between frequency and pitch?

Back

Frequency is the number of vibrations per second, and it determines the pitch of the sound; higher frequency results in a higher pitch.
