Sound Waves

Front

What is a sound wave?

Back

A sound wave is a type of longitudinal wave that is created by vibrating objects and travels through a medium such as air, water, or solids.

Front

What is pitch in sound?

Back

Pitch is the perceived frequency of a sound; it determines how high or low a sound seems to a listener.

Front

What unit is used to measure sound intensity?

Back

The intensity of sound is measured in decibels (dB).

Front

What is sonar?

Back

Sonar is a system that uses sound waves to detect objects underwater by measuring the time it takes for the sound waves to reflect back.

Front

What are ultrasound waves?

Back

Ultrasound waves are sound waves with frequencies higher than 20,000 Hz, which are above the range of human hearing.

Front

What type of wave is sound?

Back

Sound travels as a longitudinal wave, where the particles of the medium move parallel to the direction of the wave.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the maximum displacement of particles in a wave, which is related to the loudness of the sound.

Front

What is frequency in sound?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz), and it affects the pitch of the sound.

Front

What is the relationship between frequency and pitch?

Back

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

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.
