A fish is rising upward with 1 cm/sec in a container where liquid level is falling at 2 cm/sec. In the sky, a bird is diving towards the container with along the same line, then choose the correct statement(s). (Take )
Options:(select one or more)
Answer:
A, B
Solution:
Apparent-depth scaling: distances in the denser medium divide by mu for the bird, distances in air multiply by mu for the fish.
Applied to the relative speeds this gives 17/4 cm/s for the fish's image as seen by the bird and 17/3 cm/s for the bird's image as seen by the fish.
