# What are the Colours of the visible spectrum?

The colors of the visible spectrum include red, orange, yellow, green, blue, indigo, and violet.

Then, what do the colors of the spectrum mean?

Definition of spectrum for Students. plural spectra -tr? or spectrums. : the group of different colors including red, orange, yellow, green, blue, indigo, and violet seen when light passes through a prism and falls on a surface or when sunlight is affected by drops of water (as in a rainbow)

What are the colors that make up the spectrum?

• Red.
• Orange.
• Yellow.
• Green.
• Cyan.
• Blue.
• Indigo.
• Violet.
• ## What are the colors of the visible spectrum?

There are seven wavelength ranges within the visible spectrum that each correspond to a different color. The colors fall in an order commonly referred to with the acronym ROYGBIV. ROYGBIV can aid in remembering the order of the colors: red, orange, yellow, green, blue, indigo, and violet.

## What color of the visible spectrum has the shortest wavelength?

Visible light has a wavelength range of about 400 nm to 750 nm. The visible colours from shortest to longest wavelength are: violet, indigo, blue, cyan, green, yellow, orange, and red.

## Which colors have the most energy?

Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.

## Why can we see the color white?

The surface of the apple is reflecting the wavelengths we see as red and absorbing all the rest. An object appears white when it reflects all wavelengths and black when it absorbs them all. By varying the amount of red, green and blue light, all of the colors in the visible spectrum can be produced.

## What color is 400 nm?

The colors of the visible light spectrumColorWavelength intervalFrequency intervalGreen~ 560–520 nm~ 540–580 THzCyan~ 520–490 nm~ 580–610 THzBlue~ 490–450 nm~ 610–670 THzViolet or Purple~ 450–400 nm~ 670–750 THz

## Which Colour is having largest wavelength in visible spectrum?

Originally Answered: Which colour has the longest wavelength? The visible colors from Longest wavelength to Shortest wavelength are :: Red, Orange, Yellow, Green, Blue and Violet. Originally Answered: Which color of the visible light spectrum has the longest wavelength?

## Which color of the visible spectrum has the highest frequency?

The higher the frequency, the faster the oscillations and thus the higher the energy. Therefore, the highest-frequency ultra-violet light (or the lowest wavelength) is violet. However, the highest-frequency visible light would have to be roughly blue.

## What is the meaning of 1 Terahertz?

The terahertz, abbreviated THz, is a unit of electromagnetic (EM) wave frequency equal to one trillion hertz (1012 Hz). The terahertz is used as an indicator of the frequency of infrared (IR), visible, and ultraviolet (UV) radiation.

## Which color of light in the visible spectrum has the longest wavelength?

The visible colors from shortest to longest wavelength are: Violet, Blue, Green, Yellow, Orange, and Red. Infrared Radiation has a longer wavelength than visible Red light. Ultraviolet Radiation has a shorter wavelength than the visible Violet light.

## What color does a blue solution absorb?

A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light.

## Which color has the highest 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. The white light is a mixture of the colors of the visible spectrum.

## What color is absorbed by green?

A red pigment is capable of absorbing cyan light. That is, red paper can absorb both green and blue primary colors of light (recall that cyan light is a mixture of green and blue light). So red and green light shine on the paper; and green light is subtracted.

## What is the wavelength of the color white?

White light is not a color, its’a combination of all colors, the same as black is the absence of all colors. Therefore it cannot be assigned a single wavelength. White light contains all wavelengths from about 390 nm to 700 nm.

## What are the colors that make up white light?

Through his experiments with prisms, he was the first to demonstrate that white light is composed of the colors of the spectrum. Seven colors constitute white light: red, orange, yellow, green, blue, indigo, and violet.

## What color reflects the most light?

The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.

## Is white light reflected or absorbed?

If all frequencies are absorbed by the object, then it appears black. If all frequencies are reflected, then it appears white. Selective absorption describes how some frequencies of light are absorbed while others are reflected. This results in the appearance of color.

## Is ultraviolet light visible?

Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight constituting about 10% of the total light output of the Sun.

## Why does the color white reflect light?

Objects are selective about which colors they will absorb or reflect. “A black object is black because it’s absorbing all the light; it’s not reflecting any color,” Chandrasekhar says. White objects reflect all color. Your body receives part of the heat energy that the black clothing radiates.

## Why is violet the shortest wavelength?

In the visible spectrum of colors the shortest wavelength is violet. Shorter wavelength implies higher frequency and thus higher energy. Violet is right before ultraviolet on the spectrum.

## What happens when you mix all the colors of the rainbow?

In additive color mixing, like light, all the colors combined create white. Consider a prism and imagine the process in reverse. In subtractive color mixing, like paint, all the colors combined create black. Red, Blue, and Yellow can appear (when mixed in the right proportions) to make black, but it’s actually brown.
