A travelling harmonic wave is represented by the equation y (x, t) = 10–3 sin (50 t + 2x), where x and y are in meter and t is in seconds. Which of the following is a correct statement about the wave?

The wave is propagating along the

a. negative x−axis with speed 25ms^{–1}

b. The wave is propagating along the positive x-axis with speed 25 ms^{–1}

c. The wave is propagating along the positive x-axis with speed 100 ms^{–1}

d. The wave is propagating along the negative x-axis with speed 100 ms^{–1}

Y = a sin (

⇒ wave is moving along –ve -axis with speed

v= ⇒ v = = 25m/sec.
