How does photoelectric effect work?
The photoelectric effect is when light strikes a material, causing electrons to be emitted. This occurs when the photons in the light have sufficient energy to overcome the binding energy of the electrons in the material. These energized electrons are then free to conduct electricity or participate in chemical reactions.
What is ejected when light strikes a metal surface?
Electrons are ejected from a metal surface when light strikes it. This phenomenon is known as the photoelectric effect. The ejected electrons are called photoelectrons.
Reflection occurs when light strikes and then?
When the light waves strikes an object and bounces off
What occurs when light strikes a transparent surface?
When light strikes a transparent surface, it can be transmitted through the material, absorbed by the material, or reflected off the surface. The amount of light that is transmitted, absorbed, or reflected depends on the properties of the material and the angle at which the light strikes the surface.
What happens when light strikes a photosystem?
When light strikes a photosystem, it excites electrons in the chlorophyll molecules within the photosystem. These energized electrons are then passed through a series of electron carriers, generating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH. This process is called photophosphorylation and is a key step in photosynthesis.

What is the first most immediate thing that happens when light strikes chlorophyl molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.

When light energy from the Sun strikes a leaf how is the energy conserved?
When light energy strikes a leaf then chlorophill (a) present in leaf absorb that light energy . By use of that energy photosynthesis occurs.
Reflection occurs when light strikes and then?
When the light waves strikes an object and bounces off
When light strikes electrons.do the electrons reflect the light back?
Not quite. Remember that electrons are part particles and part waves. Light is given off when an electron drops from one energy state to a lower one. In answer to a different question, and may be the one you ask, When light strikes a phosphor, the electrons in the phosphor absorb energy, and give it off some time later. This is Phosphorescence.

What is the name given to a material that gives off electrons when light strikes it?
The material is called a photoemissive material.
What has to happen to replace the electrons released by chlorophyll?
Electrons released by chlorophyll during photosynthesis are replaced by splitting water molecules in the light-dependent reactions of photosynthesis. This process, known as photolysis, generates oxygen and protons, while providing electrons to keep the photosystem working.
What does light produce in a photoelectric effect?
In the photoelectric effect, light produces electrons when it strikes a material surface. The energy of the incident light is transferred to the electrons, causing them to be ejected from the material.
