Light absorbed by a chlorophyll a causes A) an electron to move from the photon to the chlorophyll. B) an electron to move from
ground state to an excited state. C) an electron to move to a neighboring water molecule. D) an electron to move from chlorophyll to ADP. E) none of the above.
B) an electron to move from ground state to an excited state.
Explanation:
Chlorophyll is a pigment that absorbs electromagnetic radiation of the visible spectrum that is used in process of photosynthesis. Chlorophyll's function is to absorb electromagnetic radiation of the visible spectrum and it absorbs blue color radiation the best and green the worst as it reflects it. It absorbs electromagnetic radiation by absorbing the energy of the photon of light by a process called charge separation.
Charge separation is the process by which an electron gets to a higher energy state by absorbing the energy of a photon.
For an object that travels at a fixed speed along a circular path, the acceleration of the object is LARGER IN MAGNITUDE THE SMALLER THE RADIUS OF CIRCLE.
<em><u>The period of a wave or periodic time is the time taken for a complete oscillation to occur. </u></em>For example its is the time taken between two successive crests or troughs.
<em><u>The beats or oscillation that occur in one second represents the frequency. Frequency is the number of complete oscillations or beats in one second in a wave.</u></em>
Frequency, measured in Hertz is given by the reciprocal of the periodic time.
Thus; <u><em>Frequency or beats per second = 1/(1/4) = 4</em></u>
