An artist has been making designs onto wood with the use of refraction of the light coming from the sun. A 31-year-old Michael Papadakis resides in Southern California, and has made the Statue of Liberty on a wooden slab, as well as mountains and animals with nothing but light and the refraction of that light (light bends towards the normal as it enters a wooden medium).
"The density of Earth's atmosphere is uneven—it decreases with increasing altitude. Light from celestial objects, including the Sun, therefore refracts multiple times when it enters the atmosphere from space.
When the light of a celestial object enters the Earth's atmosphere from space, the resulting refraction is known as astronomical refraction or atmospheric refraction. This is in contrast to terrestrial refraction that occurs when the source of light is from an object on Earth.
Light rays that travel straight down do not bend, while rays that enter the Earth's atmosphere at a shallower angle get refracted and bend towards the normal, roughly following the direction of the Earth's curvature.
This means that celestial objects in the zenith position directly above you appear in the correct position, while objects closer to the horizon appear to be higher up in the sky than they actually are.
This effect is especially powerful for objects that appear close to the horizon, such as the rising or setting Sun, because the light rays enter the Earth's atmosphere at a particularly shallow angle. Because of refraction, the Sun may be seen for several minutes before it actually rises in the morning and after it sets in the evening.
One of the consequences of this effect of refraction is that contrary to what most people think, the day and night is not exactly 12 hours long on the days of the Equinoxes. Because of refraction of sunlight, daytime is just slightly longer than night time on March Equinox and September Equinox.
This effect also has an impact on the time that the Moon can be seen before Moonrise and after Moonset."
This article goes on to talk about how atmospheric refraction manipulates our perception of the sun or moon's position. The light refracts differently in the earths atmosphere in the earth's atmosphere because it is uneven. This is what allows to see the sun a few minutes before sunrise (sunrise referring the point at which the sun crosses the horizon).
This article states that refraction is used in fiber optics by using different layers of glass with different indexes of refraction to let the light travel as far as possible. Since fiber optics can be used in communications and screens it can be an every day use of refraction.
This refraction comic is comical. The students don't understand that when a substance is removed form the water it no longer looks refracted! Light only bends when the object is submerged in the substance so as soon as the second substance is removed everything goes back to normal.
Today i was mixing something into my water and saw the spoon not appearing in its proper place in the glass. Then i remembered that its because of refraction which causes the light rays to change direction thus making the spoon look like its in a different spot.
This Khan Academy video explains total internal reflection. The video explains clearly how an incident angle larger than the critical angle results in TIR. I like how they drew out the angles and mediums while talking to show and tell. It helped me improve my understanding of the phenomenon.
This 3-panel comic shows refraction with some unexpected, permanent side effects...
This picture shows the lyrics of Diamond by Rihanna. It says that the phrase “Shine bright like a diamond” is wrong and should say “refract light like a diamond”. This is true because diamonds don't actually produce light but refract the light that shines through them.
This image explains how rainbows are made. They are made with refracted and reflected light.
