Solve this : 3 . In the diagram shown , the cylinder has height 2 H and diameter 3 H . Initially , the observer can just see the upper edge of the board . When the cylinder has been completely filled by a liquid of refractive index μ , the observer from the same position can just see the complete board . The board has a square shape with dimensions H x H . Find the value of μ . A 2 . 5 5 B 2 2 5 C 3 5 D none Share with your friends Share 1 Pintu B. answered this Dear Student , Sin iSin r =1μ⇒xx2+9H243H2-x3H2-x2+4H2=1μ .....1sin r=3H2-x3H2-x2+4H2=x2H .....2Using thi stwo equations we get ,μ=225 Hope this helps you .
