Which of the following wave functions does not represent a travelling wave?
A
y = (x – vt) 2
B
y = log (x + vt)
C
D
All of these
Text Solution
Verified by ExpertsThe correct answer is:
D
The basic requirement for a wave functions to represent a travelling wave is that for all values of x and t wave functions must have a finite value.
Out of the given functions for y no one satisfied this conditions. Therefore none can represent a travelling wave.
