Wavelength, Amplitude, Frequency

Front

What is wavelength?

Back

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

Front

What does amplitude measure in a wave?

Back

Amplitude measures the height of the wave from its rest position to its crest or trough.

Front

What is frequency in terms of waves?

Back

Frequency is the number of times a wave completes a cycle in one second, measured in Hertz (Hz).

Front

True or False: The amplitude measures the length of the wave.

Back

False

Front

What is the highest point of a wave called?

Back

The highest point of a wave is called the crest.

Front

What is the lowest point of a wave called?

Back

The lowest point of a wave is called the trough.

Front

If a wave has a high amplitude, what does that mean?

Back

A high amplitude means the wave carries more energy and has taller crests and deeper troughs.

Front

How does frequency affect the energy of a wave?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases, and vice versa.

Front

What is the formula to calculate the speed of a wave?

Back

The speed of a wave can be calculated using the formula: Speed = Wavelength x Frequency.
