Worked Solution & Example Answer:Figure 7 shows a wave on the surface of water - Edexcel - GCSE Physics - Question 5 - 2023 - Paper 1
Step 1
Which of the arrowed lines shows the amplitude of the wave?
Answer
The amplitude of a wave is defined as the maximum displacement of a point on the wave from its rest position. In Figure 7, the amplitude is represented by line B, as it shows the maximum height from the equilibrium position to the crest of the wave.
Step 2
Explain why the wave shown in Figure 7 is a transverse wave.
Answer
A transverse wave is characterized by the motion of the medium's particles being perpendicular to the direction of the wave's travel. In Figure 7, the water surface moves up and down (perpendicular to the direction of the wave's travel), demonstrating that the wave propagates through the water while the particles oscillate vertically around their equilibrium positions.
