Visible Light Spectrum Energy Levels

The emission spectrum of atomic hydrogen has been divided into a number of spectral series with wavelengths given by the rydberg formula these observed spectral lines are due to the electron making transitions between two energy levels in an atom.

Visible light spectrum energy levels. The human eye sees color over wavelengths ranging roughly from 400 nanometers violet to 700 nanometers red. Narrow spectrum blue light a k a. For an application of equation iii and the relationship between the transition energies and wavelength click on the molecular fingerprints link. The classification of the series by the rydberg formula was important in the development of quantum mechanics.

This includes wavelengths between violet and cyan in the spectrum. Essentially that equates to the colors the human eye can see. Visible light the narrow visible part of the electromagnetic spectrum corresponds to the wavelengths near the maximum of the sun s radiation curve in interactions with matter visible light primarily acts to elevate electrons to higher energy levels. At the other end of the spectrum toward red the wavelengths are longer and have lower energy figure 3.

The visible light spectrum ranges between 400 and 700 nm nanometers and are as equation iii states inversely proportional to the energy associated with the electron level transitions. This action allows the chemical mechanisms that underlie human vision and plant. Light from 400 700 nanometers nm is called visible light or the visible spectrum because humans can see it light outside of this range may be visible to other organisms but cannot be perceived by the human eye. White light may be separated into its spectral colors by dispersion in a prism.

Blue led light or short wavelength light is a type of high energy visible light defined as having a wavelength between 400 and 450 nm. The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. The visible light portion of the electromagnetic spectrum shows the rainbow of colors with violet and blue having shorter wavelengths and therefore higher energy. Visible light and near infrared light is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another.

It is also known as the optical spectrum of light or the spectrum of white light. Blue light is a range of the visible light spectrum defined as having a wavelength between 400 525 nm. A spectrum plural spectra or spectrums is a condition that is not limited to a specific set of values but can vary without steps across a continuum the word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism as scientific understanding of light advanced it came to apply to the entire electromagnetic spectrum. By definition visible light is the part of the em spectrum the human eye is the most sensitive to.

Red light has a frequency around 430 terahertz while blue s frequency is closer to 750 terahertz.
