A travelling wave pulse is given by y...

A travelling wave pulse is given by
`y=(0.8)/((3x^(2)+12xt+12t^(2)+4))`
where x and y are in m and t is in seconds. Find the velocity of the wave.

Text Solution

Verified by Experts

`y=(0.8)/((3x^(2)+24xt+48t^(2)+4))=(0.8)/(3[x^(2)+8xt+16t^(2)]+4)`
`=(0.8)/(3(x+4t)^(2)+4)`
`:.x+4t=x+vt` `:.v=4 m//s`
