Some people have suggested disposing of our nuclear waste products in the sun. However, this is a major safety issue, because the launch vehicle could explode and disperse nuclear waste in a wide area. Suppose that plutonium-239, a major nuclear waste product, has major absorption lines at 0.62 micrometers and 1.37 micrometers, with many other minor absorption lines. Using what you know about spectroscopy, describe how such waste disposal in a star could leave lingering evidence in space, even in distant galaxies. Note that the light from stars may be redshifted or blueshifted because of the star’s relative motion to other objects in the galaxy.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
