Does it reflect at the speed of light, on it's way to Earth? (or another point in the sky)

Light always travels at the same speed in a vacuum, the speed changes ever so slightly when it has to go through a different medium (water e.g.) but its so fast to begin with you wouldn't really notice it. 300,000 kilometers per second is beyond human comprehension, I mean you can only imagine how fast that is, you can't experience it or 'know' it.

Light would reflect at the speed of light. However, the appearance of speed depends quite a bit on your position relative to the direction of movement. If light is traveling away from you, and your vision could process those kinds of speeds, it would appear to move more slowly than light traveling towards you. The law of relativity would say that there are many variable we would need to look at. If you have to jets traveling from a single point on the globe, in opposite directions, going the exact same speed, the jet that was traveling with the sun would actually reach the oposite end of the globe before the other jet, even though they were both traveling the exact same speed. Light, and our perception of its movement is the basis of our measurement of time.

It reflects at the speed of light, the limit for all physical objects of our understanding. However the wavelength changes depending on the speed of the planet relative to the speed of the earth. So you can tell if it is coming or going. Getting closer or farther from earth.

Speed of light is 3x10 ^8 m/s in vaccum and in air.
After reflection on Jupitor it travels with this speed.
