Yellow light is incident upon a medium from air at an angle of 45.0°. the light bends toward the normal and refracts at 28.0°. what is the index of refraction of yellow light in this medium? dok 2 a. 1.61 b. 0.66 c. 1.51 d. 1.00

c. 1.51

Explanation:

i = angle of incidence made by yellow light at air-medium interface = 45.0°

r = angle of refraction made by yellow light at air-medium interface = 28.0°

n₁ = index of refraction of air = 1

n₂ = index of refraction of medium = ?

Using Snell's law air-medium interface

n₁ Sini = n₂ Sinr

1 Sin45 = n₂ Sin28

n₂ = 1.51

So the correct choice is

c. 1.51

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
