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?

A

`2` units, `-2` units

B

`2` units, `2` units

C

`10` units, `5` units

D

`10` units, `10` units

Text Solution

Verified by Experts

The correct Answer is:
A
`A=(10)/(5)2units`
For same particle displacement `y`, `x+2t` is
constant `:.(dx)/(dt)+2=0impliesv=(dx)/(dt)=-2`
