Question

light wavelength and depth
look at the table and diagram below. the table shows light radiation and its wavelengths. the diagram depicts a cross - section of the ocean.
use your colored pencils to color the sections in the diagram so that they correspond to the wavelength ranges listed in the table. notice that some colors of light penetrate deeper than others.

type of radiation	wavelength (in nanometers)
blue	424 - 491
green	491 - 575
yellow	575 - 585
orange	585 - 647
red	647 - 750

(there is a diagram with wavelength scale from 400 to 750 nanometers and depth scale from 0 to 80 meters, and colored sections representing different light penetrations)

1. which color penetrates deepest into ocean waters?
2. does this diagram support your observations on the other data sheets? why or why not?
3. describe the relationship between depth and an organism’s coloration.

Explanation:

To determine which color penetrates deepest, we analyze the diagram. The blue - colored region (corresponding to blue light with wavelength 424 - 491 nm) extends the deepest into the ocean depth (reaching around 80 meters or more, while other colors like green, yellow, orange, red have shallower penetration). This is because blue light has properties that allow it to scatter less and penetrate water more effectively compared to longer - wavelength colors like red, orange, etc.

Answer:

Blue (the color corresponding to the wavelength range 424 - 491 nanometers) penetrates deepest into ocean waters.
