Sound Flashcard Review

Front

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

Back

The amplitude increases.

Front

What type of wave does sound travel as?

Back

Sound travels as a compression wave.

Front

What two factors affect the speed of sound?

Back

The type of medium and the temperature of the medium.

Front

What is the energy that you can hear called?

Back

Sound.

Front

What wave interaction is represented by the bending of waves around obstacles?

Back

Diffraction.

Front

What is the definition of amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch.

Front

What is the definition of wavelength in sound waves?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is reflection in terms of sound waves?

Back

Reflection is when sound waves bounce off a surface.

Front

What is refraction in sound waves?

Back

Refraction is the bending of sound waves as they pass from one medium to another.
