Four light rays enter four long channels of optical materials from the left as show. The index of refraction for the four materials are as indicated. Air is on top of and below the four stacked optical channels. Through which channel (A, B, C, or D) could a light ray be most likely trapped totally within it after many internal reflections as it propagates toward the right?

the answer would be c

unbalanced force

explanation:

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
