A) \[Y=A(\omega \,t-kx)\]
B) \[Y=A\sin \omega \,t\]
C) \[Y=A\cos kx\]
D) \[Y=A\sin (at-bx+c)\]
Correct Answer: D
Solution :
\[y=A\sin (at-bx+c)\] represents equation of simple harmonic progressive wave as it describes displacement of any particle (x) at any time (t). or It represents a wave because it satisfies wave equation \[\frac{{{\partial }^{2}}y}{\partial {{t}^{2}}}={{v}^{2}}\frac{{{\partial }^{2}}y}{\partial {{x}^{2}}}\].
