Unit 3 Test Review

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 a disadvantage of digital signals?

Back

Digital signals can lead to more complex systems compared to analog signals.

Front

What happens to wavelength when wave frequency increases?

Back

When wave frequency increases, the wavelength decreases.

Front

What are digital signals characterized by?

Back

Digital signals are characterized by binary values, representing data in two states: 0 and 1.

Front

What is the primary function of WiFi in modern education?

Back

WiFi enables internet access for research and collaboration among students and teachers.

Front

Define Crest in the context of waves.

Back

Crest is the highest point of a wave, representing the maximum displacement from the rest position.

Front

Define Trough in the context of waves.

Back

Trough is the lowest point of a wave, representing the minimum displacement from the rest position.

Front

What is Wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the relationship between frequency and wave speed?

Back

Wave speed is equal to the frequency multiplied by the wavelength.

Front

What is the difference between analog and digital signals?

Back

Analog signals are continuous and can take any value, while digital signals are discrete and represented by binary values.
