Sound Waves

Front

What happens to the amplitude of a sound wave when the sound is produced louder?

Back

The amplitude increases.

Front

What basic behavior of sound waves does sonar technology depend on?

Back

Reflection.

Front

In a waveform resulting from the interference of two sound waves, where will the sound be the loudest?

Back

At the constructive interference point.

Front

What is true about the particles in a medium as a wave travels through it?

Back

The particles of the medium are not carried along with the wave.

Front

What happens to a fishing boat when a tsunami wave passes beneath it?

Back

The boat will bob up and down, but the wave will not carry the boat toward or away from shore.

Front

Define sound wave.

Back

A sound wave is a longitudinal wave that is created by vibrating objects and travels through a medium (solid, liquid, or gas) as a series of compressions and rarefactions.

Front

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

Back

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

Front

Explain the concept of wave interference.

Back

Wave interference occurs when two or more waves overlap and combine to form a new wave pattern, which can be constructive (amplitude increases) or destructive (amplitude decreases).

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 to the direction of wave propagation.

Front

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

Back

Approximately 343 meters per second (m/s).
