Waves Test Review

Front

What is an analog signal?

Back

An analog signal is a continuous signal that represents physical measurements. It can take on any value within a range.

Front

What is a disadvantage of analog signals?

Back

Analog signals can be distorted by background noise.

Front

What is a trough in wave terminology?

Back

A trough is the lowest point of a wave.

Front

Which electromagnetic wave has the greatest amount of energy?

Back

Gamma rays have the greatest amount of energy among electromagnetic waves.

Front

What is amplitude in the context of waves?

Back

Amplitude is the height of the wave from its rest position to its crest or trough.

Front

How is wavelength measured in longitudinal waves?

Back

Wavelength on a longitudinal wave is measured from compression to compression.

Front

What is a compression in a longitudinal wave?

Back

A compression is a region in a longitudinal wave where the particles are closest together.

Front

What is a rarefaction in a longitudinal wave?

Back

A rarefaction is a region in a longitudinal wave where the particles are spread apart.

Front

What is the difference between amplitude and wavelength?

Back

Amplitude measures the height of the wave, while wavelength measures the distance between two consecutive points in phase, such as crest to crest.

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through the vacuum of space and consist of oscillating electric and magnetic fields.
