Which of the following six functions represent a travelling wave pulse whose shape does not change with time?
Solution
For checking six functions represent a travelling wave pulse whose shape does not change with time
............ (1)
Now function
Then it's partial derivatives
And also
Then putting in equation (1)
Then velocity is found as fullfilled condition.
Now other
Then partial derivatives
And
Whicha also satisfy equation.
So this is answer.
