Refraction: When a wavelength enters a medium where its speed is lower, the wavelength changes direction.the fact or phenomenon of light, radio waves, etc., being deflected in passing Indirectly, through the interface between one medium and another or through a medium of varying density. Change in the direction of propagation of any wave as a result of its traveling at different speeds and at different points along the wave front.
Celestial Objects travelling through different mediums and entering them directly or indirectly. What changes would occur if our eyes were to see the actual event live and in slow motion. The fact that I witnessed a spacecraft flying through the Sun’s Corona and then deeper into the gas. The inferno. It came out on the East side opposite of it’s entry path BUT it appeared 10 times closer then the actual moment the spacecraft had entered. Just a few seconds before it exited and appeared on the opposite side. I believe this has to be due to the refraction of light. I believe that a fast moving object once crossing mediums and entering a medium would undergo a few forces like Gravity and Drag.
Spacecraft re-entry When an object enters the Earth’s atmosphere, it experiences different forces. Including gravity and drag. Gravity naturally pull an object back to earth. But gravity alone would cause the object to fall dangerously fast. The Earth’s atmosphere contains particles of air. As the spacecraft falls, it hits and rubs against these particles, creating friction. This friction causes the object to experience drag, or air resistance. This slows the object down and lol luckily creating a safer entry speed.
A beam of light aimed through the air will travel in a straight line. Rays of light usually travel in straight lines until they hit something.
If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. I believe that the dome of molecules and the air particles may be the reason the image we see becomes distorted, when witnessing a spacecraft re entering the Earth’s Atmosphere. I think Speed could have a major factor in it’s outcome. This ‘bending of a ray of light’ when it passes from one substance into another substance is called refraction.
Why does light bend around objects?
That is diffraction and arises from the wave nature of light. Light does bend around objects very slightly (depending on the wavelength, which is pretty tiny for visible light) but because the diffraction effect is very small you only see this when your finger tip is very close to your eyes.
