Energy,E=h*c/Wavelength h is Planks const.,c is velocity of light
diffraction goes late then the wavelenght

Each chemical element has a different spectrum; and each color has a specific wavelength.
The colors of the spectrum going from lowest energy to highest energy are violet, indigo, blue, green, yellow, orange, and red.
A color between blue and black.
Transmission of heat by radiation is due to the fact that bodies with a temperature higher than absolute zero emits photons (light) with a spectrum (distribution of energy among different color, considering also infrared, UV, X rays and so on) dependent on the body material constitution and on temperature. Remember that for photons a relationship exist between frequency (color) and energy: higher the frequency, higher the single photon energy. Thus higher the temperature higher the average emitted photon energy and higher the emitted spectrum average frequency. While emitting hot bodies slowly loose energy and cool. These photons are absorbed by other bodies, more and more efficiently while temperature of the absorbent bodies is lower and lower. When absorbed, they are transformed in heat again rising the temperature of the absorbent body. Thus, at the end, hot bodies preferentially emits photons and cool and cold bodies preferentially absorb photons and rise temperature.
When an atom is in the flame, an electron in the outer shell of that atom receives energy from the flame and jumps up to a higher shell position. This electron then falls back to is original position and in doing so emits a photon of light of a specific energy. You see this light as a color. Atoms from different elements have different numbers of electrons in their electron shells so the photons emitted as these electrons jump back are all of different energy and therefore emit light of a different color. The color of the flame in the flame test therefore helps to identify the element in the flame producing the colored light.
Red.
Violet, with a wavelenght between 380 and 450 nm, which is near the end of the visible light, next to the ultraviolet region. Be careful because talk about "colors" is quite dangerous. Firstly, different cultures has different names for the same color. In addition to this, due to the fact that the electromagnetic spectra is continuous (i.e., there are infinite's wavelenghts) it is impossible to say exactly which wavelenght is the limit of the visible region and, consequently, which is the color associate to this wavelenght. Usually (but it is a convention) it is said that visible region is between 380 and 750 nm.
black
green ~450
En electromagnetic wave is assimilable to a photon. The energy of a photon is equal to its frequency (that determines its "color") multiplied by the Planck's constant (h).
The only relationship is the 'chrom', meaning 'color'
no
Red color in the visible spectrum has longest wavelength.
the darker the color the more heat it attracts. the lighter the color the more heat it reflects.
my favorite color is purple
They both are the color of an igneous rock.
No. The color of the electron depends on the energy difference between the levels from/to which it is changing.
