Sound Waves _ Practice

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) and is created by vibrating objects.

Front

What does amplitude refer to in sound waves?

Back

Amplitude refers to the height of the wave, which determines the volume of the sound. Higher amplitude means louder sounds.

Front

What is frequency in the context of sound waves?

Back

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

Front

How does the pitch of a sound relate to frequency?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is the relationship between amplitude and volume?

Back

The greater the amplitude of a sound wave, the louder the sound is perceived.

Front

What is the zero line in a sound wave?

Back

The zero line is the baseline level of sound, representing the absence of sound pressure.

Front

How do sound waves travel to our ears?

Back

Sound waves travel through the air (or other mediums) and reach our ears, where they are converted into signals that our brain interprets as sound.

Front

What is the difference between loudness and volume?

Back

Loudness is a subjective perception of sound intensity, while volume is an objective measurement of sound amplitude.

Front

What is the role of a medium in sound wave transmission?

Back

A medium (like air, water, or solids) is necessary for sound waves to travel, as they cannot move through a vacuum.

Front

What happens to sound waves when they encounter a barrier?

Back

When sound waves encounter a barrier, they can be reflected, absorbed, or transmitted, depending on the material of the barrier.
