For a string clamped at both ends, which of the following wave equation is valid for a stationary wave set up in it? (Origin is at one end of string)
- $y = A \sin kx \sin \omega t$
- $y = A \cos kx \sin \omega t$
- $y = A \cos kx \cos \omega t$
- All of the above
Solution
Node should be at $x = 0$.
This is possible when $A_x = A \sin kx \sin \omega t$.
