Unit 3 Test Review

Front

How is the wavelength of a longitudinal wave measured?

Back

Distance between two consecutive compressions or rarefactions.

Front

What is a key characteristic of analog signals?

Back

They have infinite possible values.

Front

What part of the wave is represented by the red lines?

Back

Amplitude.

Front

How can you get a higher quality digital signal from an analog recording?

Back

Raise the sampling rate of the analog signal.

Front

What property of the wave is represented by the letter 'A'?

Back

Amplitude.

Front

Define wavelength in the context of waves.

Back

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

Front

What is the difference between analog and digital signals?

Back

Analog signals are continuous and can take on any value, while digital signals are discrete and can only take on specific values.

Front

What does amplitude represent in a wave?

Back

The maximum displacement of points on a wave from its rest position.

Front

Explain the concept of frequency in waves.

Back

Frequency is the number of waves that pass a given point in one second, 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.
