A travelling wave pulse is given by y =...

A travelling wave pulse is given by `y = (10)/(5 + (x + 2t)^(2))`
Here, `x and y` are in meter and `t` in second. In which direction and with what velocity is the pulse propagation. What is the ampitude of pulse?

Text Solution

Verified by Experts

A pulse can be expressed by the form given as `y=a/(b+ (x pm vt)^2)`
By comparing the above with the given pulse we find that the pulse is travelling along negative x-axis with velocity 2 m/s.
