Waves & Information Transfer - Unit Review

Front

What is the definition of frequency in relation to waves?

Back

Frequency is the number of complete cycles of a wave that occur in a unit of time, typically measured in Hertz (Hz).

Front

What is the relationship between frequency and wavelength when the speed of a wave is constant?

Back

Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases, and vice versa.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the primary medium through which sound waves travel?

Back

Sound waves primarily travel through air, but can also travel through liquids and solids.

Front

What is an analog signal? Provide an example.

Back

An analog signal is a continuous signal that represents physical measurements. An example is a sound wave.

Front

What is a digital signal? Provide an example.

Back

A digital signal is a discrete signal that represents data as binary values (0s and 1s). An example is binary code.

Front

How does the amplitude of a wave relate to its energy?

Back

Higher amplitude waves carry more energy than lower amplitude waves.

Front

What is the formula for wave speed?

Back

Wave speed (v) is calculated as v = frequency (f) × wavelength (λ).

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, the displacement is parallel to the direction of wave propagation.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.
