Waves, Huh What are they Good For?

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 speed of sound in air compared to in water?

Back

Sound travels faster in water than in air.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.

Front

What happens to the frequency of a sound wave as the source moves away from an observer?

Back

The frequency decreases, a phenomenon known as the Doppler effect.

Front

What is the electromagnetic spectrum?

Back

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

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence equals the angle of reflection.

Front

What type of wave is light?

Back

Light is an electromagnetic wave.

Front

In which medium do sound waves travel fastest?

Back

Sound waves travel fastest in solids.
