Info Advanced Physics: Superposition – Revision Quiz March 20, 2024 Mr Shone Advanced Physics: Superposition - Revision Quiz Test your understanding of Superposition here: 1 / 5 1) The diagram represents a stationary wave on a stretched string. What is represented by point P and by the length x? C B D A 2 / 5 2) Source S emits microwaves with constant amplitude. The microwaves hit a metal screen P and are reflected. A stationary wave is formed between S and P. The wavelength of the microwaves is much smaller than the distance between S and P. A detector Q is moved at a slow, constant speed from S to P. What happens to the amplitude of the signal detected by Q? Increases and decreases regularly Remains constant Decreases steadily Increases steadily 3 / 5 3) Where, in a standing wave, do the vibrations of the medium occur? At all points between the nodes. Only at the antinodes. At all points between the antinodes. Only at the nodes. The nodes are stationary points. All other points will be experiencing some vibrations. 4 / 5 4) The diagram shows a stationary wave on a string at two instants of maximum vertical displacement. The frequency of the wave is 12 Hz. What is the speed of the wave? 7.2 m/s 360 m/s 3.6 m/s 720 m/s 5 / 5 5) A stationary wave is produced by two loudspeakers emitting sound of the same frequency. When a microphone is moved between X and Y, a distance of 1.5 m, six nodes and seven antinodes are detected. What is the wavelength of the sound? 0.43 m 0.50 m 0.25 m 0.21 m Your score is Restart quiz
