Yes, it is true.
Whatever the colors are, the brighter light results from the beam of more photons. But each individual blue photon carries more energy than each individual red photon.
We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
In a spectrometer, each dye will absorb light of certain colors and transmit light of other colors because of the nature of the atoms of the object and the frequency of the light. If the frequency of the light is the same as the frequency that the electrons in the atoms are vibrating, then the light will be absorbed and transferred into vibrational motion.
Your question is unclear. However electron jump to a higher energy level when an atom absorbs energy.
The particular colors emitted by an element reflect the exact amounts of energy that electrons orbiting the hydrogen nucleus give off when they drop from higher energy positions further from the nucleus to lower energy positions closer to the nucleus. Since hydrogen is so small and has so few orbitals, it has only four colors that it emits on the Balmer Series. Elements with high atomic numbers have many more orbitals and thus many more colors.
There different colors emitted
There different colors emitted
There different colors emitted
The colors of light given off when an element loses energy
SPECTROSCOPE!! or a prism
The name of the range of colors emitted by a heated (energized, excited, etc...) atom is called an emission spectrum.
You and your clothes absorb some of the photons, creating the colors you see.
different wavelengths from different colours
Green, Yellow and Orange.
Green surfaces are absorbing all other color photons, and reflect only green photons, making the surface appear as green.
'Spectrum'.
Everything that is often used must have name. Such objects as colors were often used by people and people decided to give them names for simplicity. They were not invented. Only its names were invented. Colors as object are innate nature property so explanation lays in quantum electrodynamics (because colors represent photons of diffrent wave length and photons secret isn't yet enough reseached). So if you mean invention of colors as objects i.e photons - they are not invented fully yet
