The depth of a pond is 10 m. What is the apparent depth for a person looking normally to the water surface?
Given: Real depth of pond, dreal = 10 m, nw = \(\frac{4}{3}\) To find: Apparent depth Formula: n = \(\frac{Real\,depth}{Apparent\,depth}\) Calculation: From formula, ∴ Apparent depth = \(\frac{Real\,depth}{n}\) = \(\frac{10}{(\frac{4}{3})}\) = \(\frac{10\times3}{4}\) = 7.5 m
