Question

Swimmers experience decrease in visibility on diving to greater depths. Given that the mean molar absorption coefficient of sea water in the visible region is 6.2x10-5 dm3 mol-1 cm-1, calculate the depth at which a diver will experience (a) half the surface intensity of light (b) one tenth the surface intensity. (assume density of sea water = 1.03 kg dm-3)
