## Which color photon has the longest wavelength?

Red
We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.

What is the wavelength of spectral color?

The wavelengths are commonly expressed in nanometers (1 nm = 10-9 m). The visible spectrum is roughly from 700 nm (red end) to 400 nm (violet end). The letter I in the sequence above is for indigo – no longer commonly used as a color name….Color.

Wavelengths for ROYGBIV
Violet 400nm
Orange 630nm
Red 665nm

What are 7 color spectrums?

He also noted that the sequence of the colours of a rainbow never changed, always running in the same order. He coined the idea that there are seven colours in a spectrum: red, orange, yellow, green, blue, indigo and violet (ROYGBIV).

### What color has a wavelength of 434 nm?

Color Physics

Color Wavelength (nm)
Green 490 – 530
Blue 460 – 480
Indigo 440 – 450
Violet 390 – 430

Which color registered the lowest frequency longest wavelength?

Red light rays
We know that Frequency is inversely proportional to wavelength, so Red light rays have the lowest frequency and highest wavelength value. This means that Red light rays have the least number of waves in a second than any other radiation.

What are the colours in spectrum?

Newton’s colour circle combines the spectral colours red, orange, yellow, green, cyan, indigo, and blue-violet with the nonspectral colour magenta (a mixture of blue-violet and red light beams), as shown in the figure.

#### Is color a spectrum?

Light outside of this range may be visible to other organisms but cannot be perceived by the human eye. Colors of light that correspond to narrow wavelength bands (monochromatic light) are the pure spectral colors learned using the ROYGBIV acronym: red, orange, yellow, green, blue, indigo, and violet.

What is wavelength of visible spectrum?

More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
