Waves Test Review 24-25

Front

What is the definition of wavelength?

Back

The distance between two corresponding parts of a wave, such as crest to crest or trough to trough.

Front

Which bar measures the wavelength of the wave?

Back

Bar Y.

Front

What is an analog signal?

Back

A continuous signal that represents physical measurements.

Front

What is a digital signal?

Back

A discrete signal that represents data as binary values (0s and 1s).

Front

Why are digital signals more reliable than analog signals?

Back

They have less interference over long distances.

Front

What is the amplitude of a wave?

Back

The maximum distance that the wave moves from its rest position.

Front

What are the two main types of signals?

Back

Analog signals and digital signals.

Front

What is a crest in a wave?

Back

The highest point of a wave.

Front

What is a trough in a wave?

Back

The lowest point of a wave.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.
