Which of the following is true about an antinode of a standing wave on a string?
A. It is the only place where the string is moving.
B. It is the result of constructive interference.
C. It is the result of destructive interference.
D. It is a location where there is no interference.
E. It is an example of beats.
Answer:
Option B :it is the result of constructive interference.
Explanation:
Antinodes are the points on a standing wave which have maximum amplitude and this amplitude is sum of amplitudes of individual waves(which make the standing wave) so this implies they are result of constructive interference.

A jackhammer operator wears a set of protective headphones. Through the headphones, a sound wave is broadcast that is 180° out of phase with the jackhammer sound wave. The result is that he does not hear the sound of the...
Adjacent antinodes of a standing wave of a string are 20.0 cm apart. A particle at an antinode oscillates in simple harmonic motion with amplitude 0.600 cm and period 0.100 s. The string lies along the +x-axis and its left end is fixed at x = 0. The string is 70.0 cm long. At time t = 0, the first antinode is at maximum positive displacement. a. Is the right end of the string fixed or free? Explain. b. Sketch...
A series of wave fronts in a wave tank travel toward an opening in a barrier. To increase the amount of visible diffraction, one could a. increase the wave's amplitude b. decrease the wave's frequency c. increase the width of the opening in the barrier d. decrease the distance between the source of the waves and the barrier e. use a shorter wavelength 16. 17. When two wave sources are in-phase, and the wave from one source has to travel...
Indicate true or false in each of the following statements: A standing wave is the superposition of two waves The beating of two waves can be heard as a much higher frequency than the sum of the two frequencies. The second harmonic is twice times the frequency of the fundamental. Constructive interference occurs when the phase difference of two otherwise identical waves is 2π or multiples thereof. A node is a position on a standing wave of maximum displacement
Adjacent antinodes of a standing wave on a string are 15.0 cm apart. A particle at an antinode oscillates in simple harmonic motion with amplitude 0.850 cm and period 0.0750 s.

Problem A long string is fixed at one end and a standing wave is generated with a mechanical oscillator attached at one end. The opposite end of the string can be considered as a node, and treat it as the x = 0 point. The distance between adjacent nodes on the string is 20.0 cm, and an antinode oscillates with a period of 0.659 s and an amplitude of 0.550 cm. (a) Find the displacement of a point on the...
