Sound Waves

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.

What does amplitude refer to in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the volume or loudness of the sound.

How does changing the amplitude of a sound wave affect its volume?

Back

Increasing the amplitude makes the sound louder, while decreasing it makes the sound quieter.

What is frequency in relation to sound waves?

Back

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

Front

How does changing the frequency of a sound wave affect its pitch?

Back

Increasing the frequency raises the pitch, while decreasing the frequency lowers the pitch.

Front

What is pitch?

Back

Pitch is how high or low a sound seems to a listener, which is determined by the frequency of the sound wave.

Front

What happens to sound as you move further away from the source?

Back

The sound becomes quieter because the energy of the sound wave spreads over a larger area.

Front

What is the relationship between pitch and frequency?

Back

Higher frequency sound waves produce higher pitches, while lower frequency sound waves produce lower pitches.

Front

What is wavelength in sound waves?

Back

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

Front

How does amplitude affect sound quality?

Back

While amplitude affects loudness, it does not directly affect the quality or timbre of the sound.
