The displacement of a particle in a periodic motion is given by

y=4 \cos ^2(t / 2) \sin (1000 t)

. This displacement may be considered as the result of superposition of

n

independent harmonic oscillations. Here,

n

View answer and explanation

Correct option: A

Option C (

y=A \sin \left(k^2 x^2-\omega^2 t^2\right)

) is correct because it does not satisfy the standard form of a wave equation, where the arguments of the sine function should be linear in both x and t.
