130 0.751 points | Previous Arners 14mc.7 The drawing shown here represents multiple exposures of a standing wave patter produced by the interference of two traveling waves. The fixed ends of the medium are at locations Xp and xg. (a) The wavelength is represented by the distance • XA-X XI - XO X-XO (b) The points X1, X3, X, and xz represent antinodes Onodes e normal modes (c) The distance (y1 - Yo) represents o the wavelength * twice the amplitude of the original waves O one-half wavelength the amplitude of the original waves (d) If we consider the frequency of the lowest mode to be (ro), the wave source is vibrating at a frequency equal to the e eighth harmonic (aro) second harmonic(2) • fundamental (1) fourth harmonic 4fo) third harmonic (3)

Explanation / Answer

(d) As we can see ,there are 2 complete cycles of the wave in the given picture.For fundamental ,wave is only half cycle.

So here it is fourth harmonic

So 4th harmonic is the answer
