The bright light emission spectrums below are seen through a spectroscope. The unknown sample is a mixture of the observed gases

Which gases are found in the unknown sample?

gases Wand Z

gases Z and Y.

Explanation:

Photons are emitted when electrons jump from a higher energy level to lower energy level and these photons carry light energy.

The light emitted at various wavelengths produce emission spectrum, when viewed via a spectroscope.

While analyzing the image, we could see that the spectrum of unknown sample contains the gases Z and Y.

truck y has a greater velocity than truck x.

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 !

h o h o hope you have a merry christmas!
