Physical Science SPS 9 - Waves (Make- Up Work)

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

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

Front

What is amplitude?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What is a compressional wave?

Back

A compressional wave, also known as a longitudinal wave, is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is rarefaction in a compressional wave?

Back

Rarefaction is the region in a compressional wave where the particles are spread apart.

Front

What happens to wavelength when frequency increases?

Back

When the frequency of a wave increases, the wavelength decreases.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and consist of oscillating electric and magnetic fields.
