Waves and Energy Practice

Front

What is the definition of wavelength?

Back

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

Front

How is frequency defined in relation to waves?

Back

Frequency is the number of complete wave cycles 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, according to the wave equation: speed = wavelength × frequency.

Front

What is a crest in a transverse wave?

Back

A crest is the highest point of a transverse wave.

Front

What is a trough in a transverse wave?

Back

A trough is the lowest point of a transverse wave.

Front

What does the letter 'A' typically represent in wave diagrams?

Back

The letter 'A' often represents the wavelength in wave diagrams.

Front

What is the amplitude of a wave?

Back

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

Front

What is the formula to calculate wave speed?

Back

Wave speed can be calculated using the formula: speed = wavelength × frequency.

Front

What is the significance of the distance between points B and G in a wave?

Back

The distance between points B and G represents one complete wavelength.

Front

How does energy relate to wave properties?

Back

The energy of a wave is directly related to its amplitude; higher amplitude waves carry more energy.
