Unit 3: Waves Test Review

Front

What are digital signals?

Back

Digital signals are signals that represent data as discrete values, typically in binary form (0s and 1s). They are more reliable and less prone to interference compared to analog signals.

Front

What are analog signals?

Back

Analog signals are continuous signals that represent physical measurements. They can vary in amplitude and frequency, and they are more prone to interference than digital signals.

Front

What is the advantage of analog signals?

Back

Analog signals can carry more detailed information compared to digital signals.

Front

What medium do sound waves travel fastest through?

Back

Sound waves travel fastest through solids because the particles are closer together, allowing for quicker transmission of sound.

Front

What is amplitude in relation to waves?

Back

Amplitude is the height of a wave from its rest position. A higher amplitude indicates more energy in the wave.

Front

What does wavelength represent in a wave?

Back

Wavelength is 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 frequency in wave terminology?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz). Higher frequency means more waves in a given time.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength 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 = frequency x wavelength.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle movement is perpendicular to the direction of wave propagation, such as in light waves.
