What is frequency in sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound. Higher amplitude means louder sound.

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave. It is inversely related to frequency.

Front

How does wavelength affect frequency?

Back

When the wavelength is longer, the frequency is lower. Conversely, shorter wavelengths have higher frequencies.

What is the relationship between pitch and frequency?

Back

Pitch is how high or low a sound is perceived, which is directly related to the frequency of the sound wave.

What is the speed of sound?

Back

The speed of sound is the distance that sound waves travel in a given amount of time, typically about 343 meters per second in air at room temperature.

What is a sound wave?

Back

A sound wave is a longitudinal wave that consists of compressions and rarefactions as it travels through a medium.

What is the role of air particles in sound transmission?

Back

Air particles vibrate and transfer energy from one particle to another, allowing sound to travel through the air.
