What determines the color of light?
The colour of visible light depends on its wavelength. Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light.
What color does green reflect?
Colors of Objects The wavelengths that are reflected determine the color that an object appears to the human eye. For example, the leaves appear green because they reflect green light and absorb light of other wavelengths.
What happens to photons when they hit something?
Photons interact with charged particles such as electrons. When a photon collides with an electron, the photon transfers all of its energy to the electron and so poofo, no more photon.
Why do we see color electrons?
We see things because they reflect light into our eyes. If the electrons give out exactly the same light as they absorb, the substance is “colorless”.. however if the color of the light emitted is different from the color absorbed, then the substance has a color.
Why do we see green?
The reflected light from the other molecules mixes in with reflected light from the chlorophyll and influences the shade of green we perceive. Mostly the intensity of chlorophyll in plants overpowers the reflection of light from these other components and we see a predominantly green colour.
What color comes between orange and green in the visible spectrum of light?
Complementary Colors
| Color absorbed | Color seen |
|---|---|
| Blue | Orange |
| Green | Red |
| Yellow | Violet |
| Orange | Blue |
What reflects green?
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
What’s inside a photon?
Nothing is inside a photon. Photons aren’t made of anything, Photon is a particle and that has a wave associated with it and obeys wave particle duality. It is a packet of energy quanta.
What makes a photon?
A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics. A sodium vapor light energizes sodium atoms to generate photons.
What atom is green?
The colours of the various atoms within the molecules follow the standard CPK rules: Hydrogen = White. Oxygen = Red. Chlorine = Green.
What determines the color of an object?
The ‘colour’ of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.
Why do green things look green?
The colours of visible light form a colour wheel. Within that wheel the colour an object appears to be is the colour complementary to the one it most strongly absorbs. As such, plants look green because they absorb red light most efficiently and the green light is reflected.
