Pregunta 5
Pregunta
The graph shows the variation with time of the displacement X of a gas molecule as a continuous sound wave passes through a gas.
The velocity of sound in the gas is 330 m.s^–1. All the graphs below have the same zero time as the graph above.
What is the displacement-time graph for a molecule that is a distance of 0.165 m further away from the source of the sound?
