The given equation represents a stationary wave because the harmonic terms kx and ωt appear separately in the equation.
The given equation does not contain any harmonic term. Therefore, it does not represent either a travelling wave or a stationary wave.
The given equation represents a travelling wave as the harmonic terms kx and ωt are in the combination of kx – ωt.
The given equation represents a stationary wave because the harmonic terms kx and ωt appear separately in the equation. This equation actually represents the superposition of two stationary waves.
