Worked Solution & Example Answer:Figure 1 shows part of a wave - Edexcel - GCSE Physics - Question 2 - 2021 - Paper 1
Step 1
Use data from Figure 1 to calculate the wavelength of the wave.
Answer
To calculate the wavelength of the wave, we need to determine the distance between two consecutive crests. From the x-axis of Figure 1, we can observe that the distance between the first crest and the next crest is 28 cm. Therefore, the wavelength of the wave is:
Wavelength = 28 cm.
Step 2
Describe the difference between transverse waves and longitudinal waves.
Answer
Transverse waves involve oscillations that are perpendicular to the direction of wave travel. This means that the movement of the medium is up and down or side to side relative to the direction of the wave.
In contrast, longitudinal waves involve oscillations that are parallel to the direction of wave travel. This means that the medium moves back and forth in the same direction as the wave travels.
