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 is 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 wavelength?

Back

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

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 does frequency mean 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.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels in a given amount of time, calculated as speed = wavelength × frequency.

Front

What is digital coding?

Back

Digital coding is the process of converting information into a digital format that can be processed by computers.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium (like air or water) to travel through, while electromagnetic waves can travel through a vacuum.
