Wavelength color

Figure 2. The color-rendering index (CRI), of similarity to daylight-rendering, dependence upon choice of triad of spectral lights to form white light of daylight-color. Wavelengths of two components are fixed at their peaks, and the wavelength of the third component is varied. Optimum combination appears in Figure 3.

The eyeball can be calibrated to read the dispersion colors produced by the different medium-particle combinations by using Koffler glass powders as standards. The colors (wavelengths) produced by various combinations are given in tabular form by R. A. Goodman (42).

A particular color (wavelength) of light carries a particular amount of energy per photon. 

Table A.2.1 gives for radiation of a given energy the color, wavelength, wavenumber and frequency. The visible area corresponds to 400 < A < 700 nm ultraviolet radiation has A < 400 nm, infrared radiation A > 700 nm. In wavenumbers these regions are indicated as follows 14.300

When an excited electron returns to the ground state, energy is emitted as a photon is released. The color (wavelength) of the light is determined by the difference in energy between the two states (excited and ground). 

Light reflectance (reflectance, reflectivity). The fraction of the total luminous flux incident upon a surface that is reflected, generally a function of the color (wavelength) of the light.

Temperature-sensitive paints of various kinds are used to capture the temperature distribution over a surface using either the changes in color (wavelength of emitted radiation) or the intensity at a particular wavelength. Typically these use fluorescent materials. Devices range from simple stick-on tapes to expensive paints that are used on models in high-speed wind tunnel tests. 

The temperature of solar energy (sunlight) reaching the earth is approximately 6000 °C. (The temperature of light depends on the intensity of the colors, (wavelengths), not how hot it feels )...

Collimated = collinear in the same line. Monochromatic = same color (wavelength or frequency, essentially). Coherent = in phase.
