Physics - Wave on String Question with Solution | TestHub
A water wave of amplitude 0.50 m is travelling in water which is 2.0 m deep as shown in figure. Water waves travel with a speed v which is dependent on the depth of water h and is given by the equation , where g is the acceleration of free fall. As there is a greater depth of water beneath the crest of a water wave than beneath the trough, wave crests will travel faster than wave troughs.
A tilted basin contains water. Water is dripped at a constant rate into the basin as shown in the diagram below.
Options:(select one or more)
Answer:
Solution:
In the tilted basin the depth increases toward the lower side, and is larger where the water is deeper.
So the deep-water part of each wavefront advances faster, and successive drips produce wavefronts that spread asymmetrically toward the deep side.
Only pattern (A) is consistent with this; the patterns in (B), (C), (D) contradict increasing with depth and will NOT be observed.
Hence B, C, D.
