Q.15.5 (b) You have learnt that a travelling wave in one dimension is represented by a function where and must appear in the combination or , i.e. . Is the converse true? Examine if the following functions for y can possibly represent a travelling wave :
No, the given function cannot represent a travelling wave because as x and t become zero the given function won't be converging to a constant value and therefore the converse is not true.
