General Properties of waves

The crest of a wave is:

• The highest point of the wave

• The lowest point of the wave

• The distance between two successive crests

• The time of one wavelength

The trough of a wave is:

• The highest point of the wave

• The lowest point of the wave

• The distance between two successive crests

• The time of one wavelength

The wavelength $\lambda$  of a wave is:

• The highest point of the wave

• The lowest point of the wave

• The distance between two successive crests

• The time of one wavelength

The frequence f of a wave is:

• The highest point of the wave

• The lowest point of the wave

• The distance between two successive crests

• The number of waves in one second:

We measure the frequency of the wave using this unit:

• Hertz (Hz)

• metres (m)

• m/s

• Km

Here one can see:

• 1 wave

• 4 waves

• 2 waves

• 8 waves

What is the value of the wavelength of this wave?

• 0.2 m

• 0.4 m

• 0.6 m

• 0.8 m
