The equation of a wave travelling on a string stretched along the

X

-axis is given by

y = Ae^{-\left(\frac{x}{a} + \frac{t}{T}\right)^2}

(1) Write the dimensions of

A

a

and

T

. (2) Find the wave speed. (3) In which direction is the wave travelling? (4) Where is the maximum of the pulse located at

t = T

and at

t = 2T
