Students work in a small group to write down an equation for a travelling wave.
This activity follows Introducing quantum mechanics.
Write a function \(y(x,t)\) that describes the motion of this string:
You may put the origin of your coordinate system wherever you want. In your final expressions, do not use any symbolic variables except for \(y\), \(x\) and \(t\). Please do remember (as always!) to include any units that are associated with constant numbers.
First try to construct this wave on your big whiteboards and then you can check your answer by putting it into Desmos.
