Waves

Front

What is a wave?

Back

A wave is a regular disturbance that carries energy through matter or space.

Front

What is absorption in the context of waves?

Back

Absorption is the process by which a wave's energy is taken in by a material, causing the material to heat up, such as black pavement absorbing sunlight.

Front

What is a medium in wave propagation?

Back

A medium is a substance through which a wave travels, which can be a solid, liquid, or gas.

Front

What happens when a wave strikes an object and bounces off?

Back

This process is called reflection, an example of which is an echo.

Front

How does the medium affect wave speed?

Back

The speed of a wave is affected by the medium (or tension) through which it travels.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

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.
