Answer» is in DENSER MEDIUM w.r.t birdand SPEED of light is higher in rare medium as compared to denser mediumV = Vb + MU. Vb★ As we know D (apparent) = D (actuall )/ R.Ihere , observer is fish and object is bird● in this case D(apparent) > D (actual)means,Bird will APPEAR farther away from its actual distance.D (apparent ) = mu × D (actual )★ Option a is correct !Both option a and c is correcthappy to help !:) |
