Question
Sketch A shows two identical pukes traveling in opposite directions along a string. Nth with a velocity of 2.0 cm/s. After 5 ?v the string will look like which of the other sketches? Standing waves are formed when: two sinusoidal waves of the same amplitude, wavelength and frequency traveling in the same direction interfere with each other. two sinusoidal waves of different amplitude, wavelength and frequency traveling in the same direction interfere with each other. two sinusoidal waves of the same amplitude, wavelength and frequency traveling in opposite directions interfere with each other. two sinusoidal waves of different amplitude, wavelength and frequency traveling in opposite direction interfere with each other. The wave pattern in the figure shows standing waves on a string. Which harmonic of the motion is represented? first harmonic third harmonic none of the above second harmonic fourth harmonic What is the wavelength of the standing wave shown in the figure? There isn't enough information to find the wavelength. When the siring oscillates, which points isolate with the maximum amplitude? The amplitude changers with time. Cannot answer the question without knowing the time, none of the above. What is the wavelength of the standing wave shown in The figure?Explanation / Answer
5. waves superimpose linearly so they will interfare only at the point of contact and will remain unaffected for the rest of their motion. Hence the correct choice would be 1.
6. Standing waves are formed when two waves of same properties moving in opposite directin interfare. Hence the correct choice here is c.
7. This is the second harmonic also known as first overtone.
8. Wavelength means distance covered by the wave in one complete cycle which in this case is 4m hence option d.
9. Points of maximum oscillation are known as anti-nodes which in this case are x = 1 and x= 3 m so option b.
10. The wavelenth would be 3.0 m hence option c.
