Question

data sheet #4 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. which color penetrates deepest into ocean waters? what is happening to the other wavelengths of light as they penetrate the water? does this diagram support your observations on the other data sheets? why or why not? describe the relationship between depth and an organism’s coloration. bonus: on land, where the entire light spectrum is visible, what makes a red apple appear red?

Explanation:

1. The answer "Red" for the first question is incorrect. Blue - green light penetrates deepest into ocean waters because it has a shorter wavelength and is less absorbed by water molecules compared to red light.
2. As other wavelengths of light penetrate water, they are absorbed or scattered. Shorter - wavelength light like blue and green is scattered less and can penetrate deeper, while longer - wavelength light like red, orange, and yellow is absorbed more quickly.
3. Without knowing the content of other data sheets, it's hard to say for sure. But if they also deal with light penetration in water, this diagram's depiction of different light - color penetration depths can support similar observations about light behavior in water.
4. Organisms at shallower depths may have colors that match the available light (e.g., more blues and greens). Deeper - dwelling organisms may be red or black because red light doesn't reach those depths, making red - colored organisms appear black and providing camouflage.
5. A red apple appears red on land because it reflects red light wavelengths and absorbs other wavelengths in the visible light spectrum.

Answer:

1. Blue - green light penetrates deepest into ocean waters.
2. They are absorbed or scattered. Longer - wavelength lights (red, orange, yellow) are absorbed more quickly, while shorter - wavelength lights (blue, green) are scattered less and can penetrate deeper.
3. Without information on other data sheets, it's uncertain. But if they pertain to light penetration in water, it may support similar observations.
4. Organisms at shallower depths may have colors that match the available light (more blues and greens), while deeper - dwelling organisms may be red or black for camouflage as red light doesn't reach those depths.
5. A red apple appears red because it reflects red light wavelengths and absorbs other visible - light wavelengths.
