how is a rainbow formed?

Answer 1

sunlight reflects of falling rain to create prisms or a rainbow effect.

Answer 2

A rainbow is formed when water molecules in the air and white light pass at the right time. Since white light holds all colors, you can see a rainbow any time of the day, not only after a rain storm. If you have a glass pyramid around, take it out in the sun or use a flashlight to shine through the glass and on the other side a rainbow will appear.

Answer 3

The rainbow effect can be observed whenever there are water drops in the air and sunlight shining from behind the observer at a low altitude or angle. The most spectacular rainbow displays when half of the sky is still dark with draining clouds and the observer is at a spot with clear sky overhead. The rainbow effect is also commonly seen near waterfalls or fountains. Rainbow fringes can sometimes be seen at the edges of backlit clouds and as vertical bands in distant rain or virga. The effect can also be artificially created by dispersing water droplets into the air during a sunny day.

Answer 4

A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. It takes the form of a multicolored arc, with red on the outside and violet on the inside. Even though a rainbow spans a continuous spectrum of co lours, traditionally the full sequence of colors is most commonly cited as red, orange, yellow, green, blue, indigo and violet. It is commonly thought that indigo was included due to the different religious connotations of the numbers six and seven at the time of Isaac Newton's work on light, despite its lack of scientific significance and the poor ability of humans to distinguish colors in the blue portion of the visual spectrum.

Answer 5

Formation of rainbow is a natural phenomena occuring particularly in rainy season. when there are water droplets present in the atmospher, the sunlight on passing through these droplets get dispersed into its constituent colours and we can see a band of seven colours from violet to red. this spectrum is called as rainbow. The rainbow can only be seen when the light is coming from backside of the viewer and the sun is at low altitude.

Answer 6

Needs 3 things

1 drops of water in the air in sufficient numbers (usualy in the form of rain)

2 the drops of water, rain, needs to be directly illuminated by sunlight

3 you, th eobservers needs to be in the correct position to see the above 2 in a cricle 42 degrees about the anti solar point (the shadow of your head)

You will then see a rainbow.

Answer 7

As light travels through a rain drop, it's separated into it's individual wavelengths, thus different colors appear. It's the same as light shining through a piece of crystal or a prism. The "bow" is formed because there are a lot of raindrops in the sky.

Answer 8

rainbow is formed by the reflection of light

Answer 9

After rain, the sun shines on the water which made the reflectin of the sun (the sun has many colors). And that we called rainbow.
