all chemicals that can been seen by the naked eye absorb certain wavelengths of light of the visible light spectrum. it is the light that is absorbed that is what is seen. if a substance (or chemical) were to reflect all wavelengths of light (in the visible spectrum), it would be invisible.

Which components of the eye contain the pigments the absorb light energy?
The corea
What is the change that happened in each of the colors how?
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.
Why can you see the planets?
For an object to absorb light, it must be possible for photons (particles of light) to raise electrons to a higher energy level, and thus absorb the energy of the photon. If the possible energy levels of electrons don't allow this (for the particular range of energies that correspond to visible light), the photons won't be absorbed.
Energy from the sun is called what?
Energy from the sun is called solar energy. The term solar energy includes both the heat and the radiant light we get from the sun.
What is it called when heat causes an object to give off light?
energy
Substances that absorb light are converted to what?
Thermal energy
What is it called when substances give off light or another form of electromagntic radiation when they absorb energy?
fluorescence
What Substances that absorb light convert it to what energy?
Optically active
Do trees absorb light?
Yes, they do absorb light. They transfer the light-energy to chemical energy by a proces called fotosynthesis.
Inside the chloroplasts are colored substances that reflect or absorb light These substances are called blank?
pigment
What occurs when light causes electrons to move when it hits some substances?
The electrons absorb the light energy, which excites them.
What substances absorb energy from an outside source and then emit some of it as visable light even after the source is removed?
phosphorescent materials do this
Which substances is green pigment in chloroplasts that absorbs energy for photo systems?
They are the chlorophyll pigments. They absorb frequencies from visible light
What are the substances in plastids that absorb various wavelengths of light?
Pigments in plastids absorb various wavelengths of light.
Why is a green pigment needed for photosynthesis?
To absorb light energy. They are called chlorophylls
What is the function of a pigment?
they absorb light and convert it into chemical energy
What is the plant molecules that absorb energy?
chloroplast's absorb light energy
