Think About This Situation
Based
on the picture and the movie above, answer the following questions
involving light intensity.
- How does
the light change as the depth increases? Sketch a possible graph
of the (depth, light intensity) relationship that you described.
- What accounts
for the change in the light intensity?
- Suppose
you are 10 feet under water, what environmental factors determine
the light intensity at 10 feet? If you descend to 15 feet, what
determines the light intensity at 15 feet? At 20 feet? Which
of these factors remained constant and which changed?
- If I(d)
is the light intensity at a depth d, what does the quantity
I(11) – I(10) represent?
- How would
the quantity I(12) – I(11) compare to I(11) – I(10)?
What accounts for the difference?
