# Why do different colours have different wavelengths?

## Why do different colours have different wavelengths?

We see different wavelengths of light as different colors because they are associated to different wavelength, which activates different cells in the retina. You can try to answer the question from another perspective, such as why a red surface is red, but that is another story.

What are the wavelengths of a rainbow?

The colors on a primary rainbow are always in order of their wavelength, from longest to shortest: red, orange, yellow, green, blue, and violet.

What makes each color of the rainbow different?

The colours you see when a rainbow appears are the result of light being split into its various individual wavelengths. This gives us a spectrum of colours that range from the shorter blue and violet wavelengths through to the longer red wavelengths.

### Which color has the longest wavelength?

red light
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.

Which is correct color or colour?

When choosing between color and colour, keep in mind that both spellings are correct. The shorter one, color, is the preferred spelling in the United States. The rest of the English-speaking world uses the longer form, colour.

What colors are in a rainbow?

The colours of the rainbow are: Red, orange, yellow, green, blue, indigo, violet.

#### Which Colour has the longest wavelength?

Which Colour has the shortest wavelength in rainbow?

violet light
Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.

What is the colors of the rainbow?

## What are the 7 rainbow colors?

The colours of the rainbow are: Red, orange, yellow, green, blue, indigo, violet. Can you find items from around the house in each of the seven colours?

What is the Order of the rainbow colors?

The order of the rainbow is ROYGBIV (red, orange, yellow, green, blue, indigo , and violet). It is caused by a breakup of white light wavelenght (all colors) when it hits water. It is refracted as it passes through the water droplets in the sky (moisture after rain) and breaks into 7 different sizes of wavelenghts.

What is the relationship between wavelength and color?

Color is related to the frequency (or wavelength) of light. The visible spectrum runs from red, wavelength = 700 nm and f = 4.3 x 1014 to blue, wavelength = 400 nm and f = 7.5 x 1014. But temperature is also related to color. This is because hot things radiate light (for instance, the filament in an incandescent bulb).

### What color is a wavelength?

The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light.
