What is the meaning of a rainbow reflection?

A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch.


A rainbow forms when sunlight shines on water in what?

A rainbow forms when sunlight shines on water in the atmosphere.


How does the raindrops make a rainbow?

Light is refracted -- bent -- both as it enters the droplets and as it leaves. The amount of refraction is dependent on the wavelength -- the color -- of the light. IF there are droplets of just the right size and IF the sun is positioned such that its light is reflected back from the droplets, an observor between the sun and the droplets will see a rainbow.


When there is a rainbow does it actually have to be rainy?

Its does not have to be raining it must be very humid outside and sunny. A rainbow is formed when the sun shines in a certain angle on mist.


Why does the rainbow have so many colors?

Rainbows display every color in the visible spectrum of light. When sunlight hits rain droplets, it causes the light to scatter into each of its individual color components (red, orange, yellow, green, blue, indigo, and violet). The same thing happens when light shines through a prism.The rainbow's appearance is caused by dispersion of sunlight as it goes through raindrops. The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop. The overall effect is that the incoming light is reflected back over a wide range of angles with the most intense light at an angle of 40°–42°. The angle is independent of the size of the drop, but does depend on its refractive index. Seawater has a higher refractive index than rain water, so the radius of a 'rain' bow in sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows. The amount by which light is refracted depends upon its wavelength, and hence its colour. Blue light (shorter wavelength) is refracted at a greater angle than red light, but because the area of the back of the droplet has a focal point inside the droplet, the spectrum crosses itself, and therefore the red light appears higher in the sky, and forms the outer colour of the rainbow. Contrary to popular belief, the light at the back of the raindrop does not undergo total internal reflection and some light does emerge from the back. However, light coming out the back of the raindrop does not create a rainbow between the observer and the sun because spectra emitted from the back of the raindrop do not have a maximum of intensity, as the other visible rainbows do, and thus the colours blend together rather than forming a rainbow.

What happens when the sun shines and the rain falls?

a rainbow appears

Why can a rainbow form when light shines through tiny water droplets?

becasue it reflects off the water and triggers the light


When the rain stops and the sun shines how does the rainbow looks?

The rainbow soon disappears when the rain as stopped as there aren't any droplets for the light to bounce off. Hope i helped ;)


What happens to the spectrum if a red light shines on a prism?

red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.


What colors make up light white?

White Light is actually made up of all the colours in a rainbow, red, orange, yellow, green, blue, indigo & purple. An example is easy to see in a rainbow. Sunlight is white light. when it shines into water droplets in the atmosphere the colours of the light is split & forms a spectrum of colour.


What can you found when light shines through a prism?

After a rain shower you can usually see a rainbow in the sky. If you shine light through a prism you see a rainbow or more correctly the colour spectrum


What is the similarity between rainbows and prism?

They both involve a spectrum. If you shine light through a prism, it splits it up into the 7 colours of the rainbow. Rainbow is created when light shines through water, so rainbow is just another word for a spectrum. See? GCSE Physics pays off! =)


How does a rainbow get its colours?

Right after a thunderstorm, there will still be some water droplets in the sky. When the sunlight shines on these water droplets, the white light that is reflected off the water droplets is split into seven different colours: red, orange, yellow, green, blue, violet, indigo.


A rainbow forms when sunlight shines on water in what?

A rainbow forms when sunlight shines on water in the atmosphere.


Does it rain before it snows?

Because the way the sun hits the water, the water acts as a prism and divides the light into the colors of the rainbow, ROY G BIV. Also in CHRISTIAN THEORY is that it's God's promise to not flood the WHOLE Earth again. and God has kept his promise!
