Solve question 10
Q 10 How much water would be filled in a container of height 21 cm,
so that it appears half filled to the observer when viewed from the
top of the container? ( μ W = 4/3)

Decoder_2 · Accepted Answer

Let Â it be filled to height h then the part not in
water is (21-h)
so the real depth of container =Â h, and apparent depth
of water =21-h
real depth /apparent depth = refractive index of water
h21-h=433hÂ =4Ã—21-4h3h+4hÂ =4Ã—217hÂ =Â 4Ã—21hÂ =12Â cm
