When a chlorophyll molecule absorbs a photon of light, Photons strike the "antenna" of the chlorophyll molecule. This causes electrons in the photo-reaction centers that are attached to the antennas to become excited and move to a higher energy level. That's photoexcitation. The valence electrons in Magnesium (part of the chlorophyl molecule) jump to an excited state.

What happens when light hits the pigment in photosystem ll?
When light hits the pigment in Photosystem II, it excites electrons within the chlorophyll molecules, raising them to a higher energy state. This energy is then used to split water molecules (photolysis) into oxygen, protons, and electrons. The excited electrons are transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis and ultimately contributing to the production of ATP and NADPH. This occurs during the light-dependent reactions of photosynthesis.
Which pigment absorbs red and far red light in plants?
chlorophyll pigment consists of antenna and reaction centres to absorb light energy.there are two regions in this pigment that is-pigment system I which absorbs far red light at 700nm and another is pigment system II which absorbs red light at 680nm.
When white light strikes blue pigment the blue light is?
White light is composed of various colors, including blue. When white light strikes blue pigment, the blue pigment absorbs most colors of light except for blue, which is reflected back to our eyes, making the pigment appear blue.
What wavelengths of visible light are not being absorbed by red and yellow pigment?
Red pigment absorbs wavelengths of green and blue light, while yellow pigment works by absorbing blue light. Therefore, the colors not absorbed by red pigment are green and blue, and the color not absorbed by yellow pigment is blue.
A dark colored pigment that protects from the ultraviolet light is called?
Pigment that protects from the ultraviolet light is called melanin. This is science.
When light hits the pigment what to water?
refraction
What happens when pigment reflects red light?
All of the colors are absorbed.
What happens when the pigment reflects red light?
Answer #1:red light is reflected, all others are absorbed===========================Answer #2:The pigment, and anything it is shmeared on, appears red to the eye.

What happens when you shine a red light on a blue piece of paper?
The paper appears dark because red light is absorbed by the blue pigment, not reflected. The blue pigment absorbs red light and reflects blue light, which is why the paper appears blue under white light.
When a pigment reflects the red light what happens?
Answer #1:red light is reflected, all others are absorbed===========================Answer #2:The pigment, and anything it is shmeared on, appears red to the eye.
What happens when light strikes green light pigments?
The green pigment found in photosynthetic plants is called chlorophyll; it is responsible for converting sunlight.
What happens to light when it hits?
it goes nowhere
What happens when light hits a rough surface?
when light hits a rough surface it scattters.
What happens when a light hits a prism and why does it happen?
The light sctters into a spectrum.
What happens to the photo conductive layer when light hits it?
It shines by the light.
What type of reflection happens when a straight ray of light hits smooth mirrors?
When a straight light ray hits a smooth mirror, the regular reflection happens.
