Question
List down the properties required by a function to represent a travelling wave.
✓
Answer
- Any wave function should be represented by position and time. y = f(x, t).
- It should be periodic and simple harmonic. Considering the wave to move with a velocity v, the function can be represented by $\text{x}\mp\nu\text{t}'-'$ sign refers to the motion along +ve x-axis and '+' sign refers to the motion along -ve x-axis.
