Sound Waves

Front

What is Destructive Interference?

Back

Destructive Interference occurs when two waves meet and cancel each other out, resulting in a smaller amplitude or no wave at all.

Front

What is a rarefaction in a longitudinal wave?

Back

A rarefaction is a part of a longitudinal wave where the particles are spread apart, creating a region of lower pressure.

Front

What does it mean to diffract?

Back

To diffract means to bend waves around an object or through an opening, such as sound waves bending around a doorway.

Front

How does pitch relate to wavelength and frequency?

Back

The higher the pitch, the shorter the wavelength and the higher the frequency.

Front

What is pitch?

Back

Pitch is how high or low a sound is, determined by the frequency of the sound wave; higher frequency means higher pitch.

Front

What is a compression in a longitudinal wave?

Back

A compression is a part of a longitudinal wave where the particles are close together, creating a region of higher pressure.

Front

What is the relationship between frequency and amplitude?

Back

Frequency refers to how often a wave cycles per second, while amplitude refers to the height of the wave; they are independent properties.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

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.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of the wave, while in transverse waves, particles move perpendicular to the direction of the wave.
