A vessel, whose bottom is flat and perfectly reflecting, is filled with water (index = 4/3) upto a height = 40 cm. A point object in air above is moving towards the water surface with a constant speed = 4m/s. What is the relative speed of its final image (in m/s), as seen by the object itself, at a moment when the object is 30cm above the water surface?

In the figure shown M₁ and M₂ are two spherical mirrors of focal length 20cm each. AB and CD are their principal axes respectively. Which are separated by 1cm. PQ is an object of height 2cm and kept at distance 30cm from M₁. The separation between the mirrors is 50cm. Consider two successive reflections first on M₁ then on M₂. Find the size of the 2nd image (in cm)
