Question 21 (3 points) Saved day Which of the following is a solution to the wave equation, aly dt2 Oy = e-* sin (kx – wt) Oy = (cos kx) (sin t) Oy = e-* sin at y = esin x Oy = e-* cost Actually, all of these are solutions to the wave equation. Actually, none of the above is a solution to the wave equation.

Answer 1

Solving wave equation we can get the answer
