A swimmer enters a gloomier world (in one sense) on diving to greater depths. Given that the mean molar absorption coefficient of sea water in the visible region is 6.2 × 10−5 dm3 mol−1 cm−1, calculate the depth at which a diver will experience (i) half the surface intensity of light, (ii) one tenth the surface intensity. Take the absorber concentration to be 10 mmol dm−3.
