Geometrical Optics question

2023 · 13 Apr · Shift 1 · Q65

JEE MainPhysicsGeometrical OpticsNumerical+4 / −1
A fish rising vertically upward with a uniform velocity of 8 ms−18 \mathrm{~ms}^{-1}8 ms−1, observes that a bird is diving vertically downward towards the fish with the velocity of 12 ms−112 \mathrm{~ms}^{-1}12 ms−1. If the refractive index of water is 43\frac{4}{3}34​, then the actual velocity of the diving bird to pick the fish, will be ‾ms−1\underline{\hspace{2cm}}\mathrm{ms}^{-1}​ms−1.
