A "snapshot" of a wave at a given time is presented in the graph below. Match the wave's wavelength and amplitude below.

4 points
In order to determine the wavelength and amplitude of the wave, we need to understand the definitions of these terms:
- Wavelength: The distance between two corresponding points on a wave (such as the distance between two crests or two troughs).
- Amplitude: The maximum displacement of a point on the wave from its rest position.
Looking at the graph, we can observe that the distance between two consecutive crests or troughs is approximately 2 units. This represents the wavelength of the wave.
Regarding the amplitude, we can see that the wave reaches a maximum displacement of approximately 1.5 units from its rest position. This represents the amplitude of the wave.
So, the wavelength of the wave is approximately 2 units, and the amplitude is approximately 1.5 units.
