Answer:
1.324 lumens
Step-by-step explanation:
The Beer-Lambert formula gives the intensity of light in water, at a certain depth x.
In this problem, the formula given is:
where
I is the intensity (in lumens)
x is the depth (in feet)
Here we are asked to find the intensity of light at a depth of
x = 32 feet
Therefore, re-arranging the equation and substituting x = 32, we find:
lumens
