What happens to the energy carried by a wave when the amplitude increases?

Back

The energy carried by the wave increases.

Front

How does the wavelength of a high-frequency wave compare to that of a low-frequency wave?

Back

A high-frequency wave has a shorter wavelength than a low-frequency wave.

Front

What is the relationship between wavelength and frequency?

Back

A wave with short wavelengths has a high frequency.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

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

Back

Speed = Wavelength × Frequency.

Front

If a wave has a wavelength of 8 cm and a frequency of 2 Hz, what is its speed?

Back

Speed = 8 cm × 2 Hz = 16 cm/s.

Front

What type of wave has the highest frequency: sound waves, light waves, or radio waves?

Back

Light waves have the highest frequency.

Front

What is the effect of increasing frequency on wavelength?

Back

Increasing frequency results in a shorter wavelength.

Front

What is the amplitude of a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.
