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?
[object Object]
What occurs when light causes electrons to move when it hits some substances?
The electrons absorb the light energy, which excites them.
What type of reflection occurs when light strikes a surface at many points that all bounce off in the same direction?
regular reflection
What is the effect of frequency of incident light on photoelectric current?
The photoelectric effect is based on two principles. 1. The intensity or brightness of the visible light (number of photons): The higher the intensity (larger number of photons) determines the number of electrons that are released from the surface material. 2. The frequency of visible light (wavelength): The higher the frequency a beam of light has when it strikes the surface determines the speed (kinetic energy) of the electrons that are ejected from the material. This is independent from light intensity. The higher the frequency of the light, the higher the energy of the electrons emitted, and thus, the higher the current of the circuit.

What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
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.
What occurs when light causes electrons to move when it hits some substances?
The electrons absorb the light energy, which excites them.
What has to happen to replace the electrons released by chlorophyll?
Electrons are replaced with splitting water when light strikes chlorophyll.
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.
This stack of thylakoids catches the light?
When light strikes a thylakoid, energy is transferred to electrons which cause them to jump to a higher energy level... the electrons are now "Excited". Hope this helps :D
What type of reflection occurs when light strikes a surface at many points that all bounce off in the same direction?
regular reflection
What heppens when light strikes green plant pigments?
electrons become excited
