Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that transfers energy through the vibration of air molecules.

Front

How does energy transfer occur in a sound wave?

Back

Energy transfer in a sound wave occurs as air molecules vibrate back and forth, creating areas of compression and rarefaction.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Front

How does amplitude relate to the energy of a wave?

Back

Higher amplitude indicates greater energy in the wave, while lower amplitude indicates less energy.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

How do you calculate the number of wavelengths in a given distance?

Back

To calculate the number of wavelengths in a distance, divide the total distance by the wavelength.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, and vice versa.

Front

What is the formula for wave speed?

Back

Wave speed can be calculated using the formula: Wave Speed = Frequency x Wavelength.

Front

What is the significance of the speed of sound in air?

Back

The speed of sound in air is approximately 343 meters per second at room temperature, and it varies with temperature and pressure.

Front

What factors affect the speed of sound?

Back

The speed of sound is affected by the medium through which it travels, temperature, and pressure.
