The intensity I of light at a depth of x meters below the surface of a lake
Question:
The intensity I of light at a depth of x meters below the surface of a lake satisfies the differential equation dI/dx = (-1.4)I.
(a) At what depth is the intensity half the intensity I0 at the surface (where x = 0)?
(b) What is the intensity at a depth of 10 m (as a fraction of I0)?
(c) At what depth will the intensity be 1% of that at the surface?
