Properties of Waves (Wavelength & Amplitude)

Front

What is a wave?

Back

A disturbance that transfers energy from place to place through matter or space.

Front

What does wavelength measure?

Back

The distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What does amplitude measure?

Back

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

Front

Which letter represents wavelength in a wave diagram?

Back

A (assuming A is the label for wavelength in the diagram).

Front

Which letter represents amplitude in a wave diagram?

Back

B (assuming B is the label for amplitude in the diagram).

Front

How is wavelength related to frequency?

Back

Wavelength is inversely proportional to frequency; as wavelength increases, frequency decreases.

Front

What is the formula for wave speed?

Back

Wave speed = Wavelength × Frequency.

Front

If a wave has a wavelength of 4 meters and a frequency of 2 Hz, what is its speed?

Back

Wave speed = 4 m × 2 Hz = 8 m/s.

Front

What happens to the amplitude of a wave as energy increases?

Back

The amplitude increases as the energy of the wave increases.

Front

What is the relationship between amplitude and sound volume?

Back

Higher amplitude waves produce louder sounds, while lower amplitude waves produce softer sounds.
