A standing wave of a string fixed at both ends which has 4 antinodes is known as theQuestion 15Select one:A.the fourth harmonic.B.the second harmonic.C.the fifth harmonic.D.the first harmonic.E.the third harmonic.

For a standing wave on a string the wavelength must equal:Select one:a.the distance between adjacent nodes.b.the distance between supports.c.twice the distance between adjacent nodes.d.the distance between adjacent antinodes.

A 50.0-gram, 7.20-meter string is subject to a tension force of 45.0 N, with both ends fixed. Adopt a coordinate system in which the string lies along the x-axis, with one end at x = 0 and the other at x = 7.20 m.(a)Determine the positions (x-values) of the nodes and antinodes when the string is exhibiting the third harmonic. (Enter your answers, in m, from smallest to largest.)1st node x = m1st antinode x = m2nd node x = m2nd antinode x = m3rd node x = m3rd antinode x = m4th node x = m(b)At what frequency (in Hz) does this third harmonic vibrate? Hz

n the context of standing sound waves, explain clearly what is meant by each of the following terms: nodes, antinodes, harmonic frequencies

A string is fastened at both ends.  If you pluck the string in the middle, you will hear a note withQuestion 9Select one:A.the fundamental frequency and the odd harmonics only.B.the fundamental frequency and the even harmonics only.C.the fundamental frequency and the second harmonic only.D.the fundamental frequency and all the harmonics.E.the fundamental frequency only.

Two waves of equal frequency and amplitude are travelling in opposite directions along a stretchedstring. When they meet, they form a stationary wave with three nodes and two antinodes.The frequency of both waves is doubled and a new stationary wave is formed.How many antinodes are there in the new stationary wave?A 1 B 2 C 3 D 4
