A harmonic source (S) is driving a taut string. The other end of the string is tied to a wall that is not so rigid. It is observed that standing waves are formed in the string with ratio of amplitudes at the antinodes to that at the nodes equal to 8. What percentage of wave energy is transmitted to the wall?
