The displacement of a particle executing periodic motion is given by

y = 4\,\,{\cos ^2}\left( {t/2} \right)\,\,\,\sin \,\,\left( {1000\,t} \right)

. This expression may be considered to be a result of superposition of

View answer and explanation

Correct option: B

Three waves

Option B (Three waves) is correct because the given expression can be decomposed into three sinusoidal waves using trigonometric identities.
