8 - Mechanical Waves

Front

What is the definition of frequency in the context of mechanical waves?

Back

Frequency is the number of wavelengths that pass a point each second, measured in Hertz (Hz).

Front

What is the lowest point on a wave called?

Back

The lowest point on a wave is called the Trough.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum; it requires a medium such as solid, liquid, or gas.

Front

What are the two types of mechanical waves?

Back

The two types of mechanical waves are longitudinal waves and transverse waves.

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is the wavelength of a wave?

Back

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

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 a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particles of the medium move perpendicular to the direction of the wave's travel.
