chemistry (a) 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 $6.2 \times 10^{-3}\ \mathrm{dm}^{3}\ \mathrm{mol}^{-1}\ \mathrm{cm}^{-1},$ calculate the depth at which a diver will experience (i) half the surface intensity of ...
