Using the photo's scale of "0.15 m" per unit, the wave's approximate amplitude is 0.3 meters, and its approximate wavelength is 0.6 meters, determined by measurement.
Step 1: Identify the scale
The scale in the photo is labeled "0,15 m". This means that each unit on the scale is equal to 0.15 meters.
Step 2: Measure the amplitude of the wave
The amplitude of a wave is the distance from the crest of the wave to the trough of the wave. In the photo, the amplitude of the wave is approximately 2 units on the scale. This means that the amplitude of the wave is approximately 2 * 0.15 m = 0.3 meters.
Step 3: Measure the wavelength of the wave
The wavelength of a wave is the distance between two consecutive crests (or troughs) of the wave. In the photo, the wavelength of the wave is approximately 4 units on the scale. This means that the wavelength of the wave is approximately 4 * 0.15 m = 0.6 meters.
Conclusion
The approximate amplitude of the wave in the photo is 0.3 meters. The approximate wavelength of the wave in the photo is 0.6 meters.
