Identify which one of the following will NOT satisfy the wave equation

1.	Identify which one of the following will NOT satisfy the wave equation.(a) 50e^j(wt – 3z)(b) sin(w(10z + 5t))(c) cos(y^2 + 5t)(d) sin x cos tThis question was addressed to me during an interview.Origin of the question is Advanced and Tricky Questions in division Advanced and Tricky Questions of Electromagnetic Theory
Answer» The correct answer is (C) cos(y^2 + 5T) Explanation: The WAVE cos(y^2 + 5t) does not SATISFY the general wave equation. Thus it is not an electromagnetic wave.
