A snapshot graph of a travelling wave is shown. The wave is travelling to the right at 50.0 m/s. What is the amplitude if the maximum displacement is 38.0 cm and the total distance travelled by the wave is 16.0 m?
38.0 cm
To find the amplitude of the travelling wave, we need to understand some key concepts.
1. Amplitude: The amplitude of a wave is the maximum displacement of particles from their equilibrium positions. In other words, it represents the height or magnitude of the wave.
2. Total Distance Traveled: The total distance traveled by the wave is the sum of the distances traveled by individual particles during one complete cycle of the wave.
In the given question, we are given the maximum displacement (38.0 cm) and the total distance traveled (16.0 m). We also know that the wave is traveling to the right at 50.0 m/s.
To find the amplitude, we can use the following formula:
Amplitude = Maximum Displacement / 2
Given that the maximum displacement is 38.0 cm, we can convert it to meters by dividing it by 100:
Maximum Displacement = 38.0 cm / 100 cm/m = 0.38 m
Now, we can calculate the amplitude:
Amplitude = 0.38 m / 2 = 0.19 m
Therefore, the amplitude of the travelling wave is 0.19 m.
