A fish rising vertically to the surface of water in a lake uniformly at the rate of 2 m /s observes a kingfisher diving vertically towards the water at the rate of 10 m/s. If refractive index of water is n=4/3, what will be the actual velocity of the kingfisher

as the fish is in water this means the observer is in the denser medium. so for it the king fisher is at x+mew y , here x is the depth of which fish and y is height of kingfisher from surface of water , mew is the refractive index of water , which is 4/3. now if yow differentiate this result you will get the velocity of bird as seen by crow. here v= v1+ mew v2 , here its value will be 2+4/3 v2= 10 , by this you can calculate the speed of bird.

taking relative velocity in consideration the speed of Kingfisher seen by fish(rest) is 8m/s. now apparent height(h)=real height (d) ×nh=d×ndiiff. dh/dt= n dd/dt8=4/3 × dd/dtdd/dt=6. thank you.
