Waves

Front

What is a wave?

Back

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

Front

What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is the definition of frequency?

Back

Frequency is the number of vibrations or cycles that occur in a unit of time, usually measured in Hertz (Hz).

Front

What is wavelength?

Back

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

Front

How does density affect the speed of sound?

Back

Sound travels faster in denser mediums because the particles are closer together, allowing the sound waves to transmit energy more efficiently.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, arranged by wavelength and frequency.

Front

What is the difference between compressions and rarefactions in a sound wave?

Back

Compressions are regions where particles are close together, while rarefactions are regions where particles are spread apart.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is an example of a mechanical wave?

Back

Sound waves traveling through air or water.

Front

What is an example of an electromagnetic wave?

Back

Light waves, radio waves, and X-rays.
