A bird in air is dividing vertically over a tank with speed $6cm/s$. The base of the tank is silvered. The fish in the tank is rising upward along the same line with speed $4cm/s$. (Take: ${\mu }_{\text{water}}=4/3)$. Find:
(a) The speed of the image of the fish asseen directly by the bird.
(b) The speed of the image of the bird relative to the fish looking upwards.

A man runs towards a mirror at a speed $15m/s.$ The speed of the image relative to the man is

Find out the following in the figure shown below :
(a) The apparent speed of the fish as observed by the bird
(b) The apparent speed of the bird as observed by the fish

Falcon is a bird which flies with a maximum speed of 320 $km/h$. Calculate its speed in $m/s$.

The speed of the effux from an open tank is identical to that of $\text{\_\_\_\_\_}$

A fish is 60 cm under water $(\mu =4/3)$. A bird directly overhead looks at the fish. If the bird is at a distance of 120 cm from the water surface, (a) What is the apparent position of the fish as seen by the bird and (b) what is the apparent position of the bird as seen by the fish?

In the previous question, if the bird is diving vertically down with speed =6m/s , his appearent speed as seen by a stationary fish underwater is

A bird is flying $3m$ above the surface of water,If the bird is diving vertically down with speed $=6m/s$his apparent velocity as seen by a stationary fish underwater is:

A bird in air looks at a fish vertically below it and inside water. $h_1$ is the height of the bird above the surface of water and $h_2$, the depth of the fish below the surface of water. If refractive index of water with respect to air be $\mu$, then the distance of the fish as observed by the bird is
