Sound and Waves Flashcard

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch.

Front

What is the relationship between energy and amplitude of a sound wave?

Back

Energy is directly proportional to the square of the amplitude.

Front

How many states of matter are there? What are they?

Back

Five: Solid, Liquid, Gas, Plasma, Bose-Einstein Condensate.

Front

What is a common cause of hearing loss?

Back

Exposure to loud noise.

Front

What is a medium in the context of sound waves?

Back

A substance through which something is transmitted.

Front

Define sound wave.

Back

A sound wave is a longitudinal wave that is created by vibrating objects and propagated through a medium.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the particle displacement is parallel to the direction of wave propagation, while in transverse waves, the particle displacement is perpendicular.

Front

What is resonance in the context of sound?

Back

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

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
