Alaser with a wavelength of 532 nm is aimed horizontally at a diffraction grating with 580 grooves per mm in a large, dark room. the grooves are oriented vertically. the laser is 2.7 m away from the diffraction grating, while a flat, white wall is 3.9 m behind the diffraction grating. describe what appears on the wall and where.

that would be b i just took the test : )

answer and explanation;

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.

there are no components of a physical goal mentioned on the list of choices that you've provided.
