# What Color Has The Highest Frequency?

## Help Please!!! What is the relationship between the fre- quency of light and its color?

What is the relationship between the fre- quency of light and its color? 1. The highest-frequency light we detect ap- pears to most people as the color red. 2. There is no relationship between the fre- quency of light and its color. 3. The lowest-frequency light we detect ap- pears to most people as the color violet. 4. Lights of different frequencies are per- ceived as different colors. 5. None of these

The answer will be 4(if you are only considering visible light). 1 and 3 are the opposite of what happens in the visible spectrum. Higher frequency corresponds to higher energy, and violet light has more energy than red light.

The truth is most light can not be detected by human eyes(i.e. they have no color) gamma rays, x-rays, uv light, infrared light, microwaves, radiowaves...this is all the same as visible light, just in different frequencies.

## what are the colors of the rainbow ?

and what order do they move in ?

The colors of the rainbow, which are also the colors found in the visible portion of the electromagnetic spectrum, are:

Red, Orange, Yellow, Green, Blue, Indigo, and Violet

The color with the longest wavelength and lowest frequency, which is red, is placed at the top. The color with the shortest wavelength and highest frequency, which is violet, is placed at the bottom.

## Which colour, red or blue, has the higher frequency and which has the longer wavelength?

Which colour, red or blue, has the higher frequency and which has the longer wavelength?

The two other people are either dopes or mocking you.

It is that FREQUENCY is what specifies color...not wavelength.

Blue ALWAYS has higher frequency than red. Violet is the visible color of highest frequency, red is the visible color of lowest frequency.

For either free space or any material I classify as by my made-up word "isohertzic", the relation is that wavelength is inversely proportional to frequency in order to satisfy v = lambda*f.

Because of the inverse proportional trend, I suggest careful adjective use:

For frequency, common usage suggests always using high and low. If I had my way, I would use the words often and seldom in order to consider what frequency actually implies. For instance: blue has an often frequency, red has a seldom frequency. BUT, this will not catch on in common use.

For wavelength, it is a length! Use the words long and short.

So:
Red: low frequency, long wavelength (two L adjectives for you)
Violet: high frequency, short wavelength

In the case of light in empty space, the wavespeed is c, the speed of light. And hence, c = lambda*f is what must be satisfied.

In any transparent material, effective wavespeed is actually less, and as per definition of refractive index (n), the equation c/n = lambda*f needs to be satisfied.

"isohertzic" is my term for a material which has n being a constant value and independent of frequency. The opposite is my made-up term of "anishertzic".

Air is an example of an isohertzic material.
Flint glass is an example of an anishertzic material, and is of interest for construction of the famous prism.

Water is a naturally occurring anishertzic material, and is why the rainbow is a phenomena of nature after rainstorms.

## smart people:what do all the color stuff have to do with the electromagnetic spectrum?

u see i have a project due soon and i know not a lot about the electromagnetic spectrum, i just know the types of radiation in it. i know the frequency, wavelength crap but i dont know the temperature colorful visible light stuff that you see on the diagram. it would be splendid if someone could explain the diagram to me and the different color scale things on it.... also why are all the diagrams different? http://mynasadata.larc.nasa.gov/images/EM_Spectrum3-new.jpg and http://praxis.pha.jhu.edu/science/emspec.html etc. please save my life! thank you and why is the temperature color range different in every diagram?

Color *is* frequency, for visible light.

Color is irrelevant for all other electromagnetic waves...they have no color, except when a false-color display of a detector shows so.

## List the colors of the spectrum of white light starting with the color of lowest frequency?

also with the color of shortest wavelength.

The lowest frequency of visible light (and thus energy), goes like this:

red, orange, yellow, blue, indigo, violet

starting with the shortest wavelength, and thus the highest energy:

violet, indigo, blue, yellow, orange, red.
