a mirage
the bending of light when passing through an object
When you see a transparent object in a clear liquid, it is due to the principles of refraction and transmission of light. Light passes through the transparent object and is bent or refracted when it enters the object, which allows you to see the object's shape. Additionally, the contrast between the object and the liquid allows you to visually distinguish them.
Scientist investigate the early universe by observing objects that are extremely far away in space.Beause it takes time for light to travel through space,looking through a telescope is like looking back in time one travels. Looking at distant galaxies evolve through time and perhaps what caused them to form in the first place.Scientiiist have already found some very strange looking objects in the Early universe.
The image of a distant object is brought into focus in front of a person's retina, the defect is called nearsightedness. A virtual image produced by a lens is always located in front of the lens.
The bending of light from distant galaxies is primarily caused by gravitational lensing, a phenomenon predicted by Einstein's theory of general relativity. When light from a distant galaxy passes near a massive object, such as another galaxy or a cluster of galaxies, the gravitational field of that object warps the space around it, causing the light to follow a curved path. This bending can magnify and distort the appearance of the distant galaxy, allowing astronomers to study objects that would otherwise be too faint or obscured.
A mirage is an image of a distant object caused by refraction of light. This phenomenon occurs due to differences in air temperature causing light to bend, creating the illusion of an object where it is not actually located.
Refraction
Mirage
It's called refraction.
When an object appears distorted in water, it is called refraction. Refraction occurs because light travels at different speeds in water compared to in air, causing the object to appear shifted or distorted when viewed through the water.
When a wave strikes an object and bends around it, it is called diffraction. This phenomenon occurs when waves encounter an obstacle or aperture and spread out in different directions, resulting in the bending of the wave.
reFRACtion There isn't a good nmeonic or the like to remember the difference between refraction, reflection and diffraction. You just have to learn it.
Refraction of light allows for the change of appearance of an object
Distance objects can be seen to "ripple" on a hot day because of refraction. As light from a distance object makes the trip to the observer, it passes through air of slightly varying densities. This causes it to "change course" to a degree, which is refraction. It is this thermally induced refraction that is responsible for the "ripple" we see, and for the mirage we sometimes hear about.
The bending of a wave as it moves from one medium into another is called refraction.
Refraction. This is when light changes direction as it passes from one transparent medium to another with a different optical density, causing it to bend.
because of refraction , you see the object "bending"
