Question 6(multiple choice worth 2 points) select the statement that correctly describes how light travels? light can travel in a vacuum, and its speed is constant even if the light source is moving. light can travel in a vacuum and will travel slower if the light source is moving in the same direction. light can travel in a vacuum, and it travels faster if the light source is stationary. light travels only through a medium, it travels faster if the light source is stationary.

I believe the answer is the first one.

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.
