- 1. Multiple ChoiceA standing wave is formed on a string. Which of the following statements is/are true?
∎ Progressive waves are travelling along the string in both directions.
∎ The standing wave is an example of superposition.
∎ The wavelength of the standing wave is d.1, 2 and 3Only 1 and 2Only 2 and 3Only 1 - 2. Multiple Choice
The diagram shows the standing wave pattern of a vibrating string which is fixed at ends X and Y.
Which one of these statements is true?P to R is one wavelength.At R the string will move up.The lowest frequency for this string is one third of its current value.The kinetic energy of the string is at its maximum value. - 3. Multiple ChoiceA receiver R is moved from S (a reflector) towards T (a transmitter). The intensity changes as in the diagram. Which of the following statements is correct?R is measuring the amplitude.The frequency of the microwaves is 2.5 GHz.The wavelength of the microwaves is 6.0 cm.The amplitudes of the transmitted and reflected waves are always equal.
- 4. Multiple ChoiceThe moving black dot is called:a nodean anti-nodean anti-amplitudethe wangy bit
- 5. Multiple ChoiceThe stationary dot is called:a node.an anti-node.the amplitude.the not moving bit.
- 6. Multiple ChoiceWhich harmonic is shown?1st2nd3rd4th
- 7. Multiple ChoiceWhich harmonic is shown?2nd3rd4th5th
- 8. Multiple ChoiceA standing wave:transports energy but does not move.is composed of a single travelling wave.stores energy.makes a loud noise.
- 9. Multiple ChoiceWhat are the boundary conditions for these standing waves?Anti-nodes at each end.The surface of the string is smooth.The string is free at both ends.There is a node at each end.
- 10. Multiple ChoiceThe string is 3.5m long. Measure the time period and hence calculate the speed of the underlying travelling waves.0.7ms-11.4ms-12.8ms-13.5ms-1
