Describe how fans in a sporting stadium would need to move to create a transverse wave and a longitudinal wave
To create a transverse wave in a sporting stadium, the fans would need to coordinate their movements in a way that causes a disturbance perpendicular to the direction of the wave propagation. Here's how they can achieve this:
1. Choose an axis: Fans should decide on a particular axis or line along which they want the transverse wave to move. For example, they may choose to align themselves from one end of the stadium to the other.
2. Orient themselves: Once the axis is defined, fans need to position themselves on the axis such that they are facing the same direction. For instance, if the chosen axis is along the length of the stadium, fans should all be facing towards either the left or right side of the stadium.
3. Sequentially stand and sit: Fans can create a transverse wave by standing up and sitting down in a sequential manner. Start with a group of fans near one end of the stadium standing up, then gradually proceed along the axis, with each group of fans standing up as the wave reaches them and sitting back down once the wave passes. This sequential movement creates the visual effect of a moving wave, resembling the movement of the sea waves.
To create a longitudinal wave in a sporting stadium, fans would need to coordinate their movements in a way that causes a disturbance parallel to the direction of the wave propagation. Here's how they can achieve this:
1. Spread out evenly: Fans should spread out evenly across the stadium, maintaining a constant distance from one another.
2. Sequentially push forward and pull back: To create a longitudinal wave, fans need to push forward and pull back in a sequential manner. Start with a group of fans near one end of the stadium pushing forward, then gradually proceed along the stadium, with each group of fans pushing forward as the wave reaches them and then pulling back once the wave passes.
By synchronizing their movements, the fans can create a disturbance that travels through the stadium as a longitudinal wave, resembling the movement of a slinky or a coiled spring expanding and contracting.
