Transparency of a Lake. Environmental scientists measure the intensity of light at various depths in a lake to find the “transparency” of the water. Certain levels of transparency are required for the biodiversity of the submerged macrophyte population. In a certain lake the intensity of light at depth is given by where I is measured in lumens and in feet.
Find the intensity I at a depth of 30 ft.
