What are examples of refractions? Explain how it works.?

Answer 1

Rainbows are a common example of refraction. A prism is the classic example by which to demonstrate refraction.
Refraction is a process in which light is broken up into its component colors. Most transparent materials through which light passes will bend each color (wavelength) of the spectrum of that light source depending on the wavelength of each color. Some colors are bent more and some less. That's why we see a rainbow: sunlight, which surprisingly is made up of all colors, shines on a raindrop or droplet of water and as it passes through it the rays are refracted (broken up) into the colors of the rainbow and that light reflects off the back of the droplet as the spectrum of light that we see. What we see is ROYGBIV, or Red, Orange, Yellow, Green, Blue, Indigo, and Violet. We see a rainbow because we are actually looking at millions of droplets.
The amount that any given material bends light waves is known as its index of refraction. Neat, huh?

Answer 2

Put a pencil in a glass of water. See it from its side. You will see the bend in the pencil even though it is straight.This is because the light rays bent when passing through different mediums. The total refraction is called reflection.What you see in your mirror is reflection.What you see from a prism is because of refraction.

Answer 3

refracting telescope [ the original type of telescope]......light from a star is bent and focused .....same goes for camera lens, eyeglasses, etc...........

refraction [ or bending ] of water waves as the wave moves from deep to shallow water....[ at an angle ]..........

Refraction is caused by the difference in speed between two media [ air and glass, water and air, even deep and shallow water ] as a wave moves from one material to another, at an angle...............sound, light , water waves are the types of waves usually seen to refract, though there are other examples.........

For example, light moves slower in glass than in air [ think about all of those atoms in the glass slowing the light down ....and the glass is denser than air, so it has a lot more atoms....], so when light enters glass at an angle, it does not follow the straight line that it was moving "along", but refracts , or bends, to follow a new path thru the glass........see Snell's law of refraction, if you want more physics............

Answer 4

examples of refraction is like the water in the swimming pool it works when the light bends when it goes through one transparent medium into another

Answer 5

you will discover the pehenomenon of diffraction once you're taking a gla of water and ut a pencil or an spoon in it; once you look on the factor of the glass, the spoon or pencil seems to be broken. off beam this would not be the case; because of the fact the easy refracts while it passes from air to glass, to water (all distinctive fabric with distinctive densities), the easy bends (breaks) while passing those components. the image that's in this occasion seen by way human beings, additionally seems to be "broken" that's a similar central that motives ligt to break while passing from air to a raindrop. the easy bends. distinctive wavelengths (and in this occasion distinctive colours) do not bend the two (some bend extra effective than others). this way, the sunlight is divided u in all its distinctive colours while assing via raindrops, and that's in many situations seen as a rainbow.

Answer 6

Eye Glasses. Lenses.
Convex - bends the rays of light towards the centerline of the lens ... like a magnifying glass.
Concave - bend the rays of light away from the centerline of the lens ... like my glasses.

Answer 7

Rainbows, halos, bending of objects in water.

Light travels by the shortest path (by time).
