If wave

y = a\,\,\cos \left( {\omega t + kx} \right)

is moving along

x - axis

, the shape of pulse at

t = 0\,\,and\,\,t = 2\,s

View answer and explanation

Correct option: B

Are same

Option B (Are same) is correct because the shape of the pulse is determined by the cosine function, and the cosine function repeats its shape after a certain time period if no changes are made to the wave.
