Name three things that can happen to light energy (solar radiation) after striking a leaf.
Homework Answers
Sunlight is essentially needed for the process of photosynthesis. Leaves have specialized organs within their cells called chloroplasts . After striking of sunlight over a leaf , chlorophyll pigments absorb specific wavelengths from the sunlight . These are mainly red and blue.
Chloroplasts contain two types of chlorophyll . A and B . A absorb blue ,red ,violet lights and B absorbs mostly blue light .
These chlorophyll have specific proteins called P700 and P 680 . They convert photons that is light energy to chemical energy.
Using this chemical energy sugar is produced by photosynthesis.

Sunlight hits the solar cell below and three things happen: some light is reflected by the solar cell; some light is converted to electrical energy; and the air around the solar cell heats up a bit. The energy flow diagram for the system that includes the sun and a photovoltaic (or solar) cell is shown below on the right A. Which form(s) of energy belong to the system? Note that Elight represents the light reflected by the solar cell. (Select...

A green leaf has a surface area of 2.10 cm2. If solar radiation is 1200 W/m2 , how many photons strike the leaf every second? Assume three significant figures and an average wavelength of 504 nm for solar radiation.
What colour of the visible light spectrum striking your solar cell are being absorbed by it?...
What colour of the visible light spectrum striking your solar cell are being absorbed by it? What would happen to its power efficiency if a filter of the same color as the anthocyanin was placed over your cell? The solar cell is a TiO2 solar cell which utilizes raspberries.

A solar cell (0.9 cm2 ) receives solar radiation with photons of 1.8 eV energy having intensity of 0.9 mW/cm2 . Measurements show open-circuit voltage of 0.6 V/cm2 , short-circuit current of 10 mA/cm2 , and maximum current is 50% of the short-circuit current. Efficiency of the cell is 25%. Calculate the maximum voltage that the cell can provide and the Form Factor

The reason there is danger in exposure to high energy radiation is that the radiation can rupture chemical bonds. In some cases cancer can be caused by it. A C-C single bond has a bond energy of aprox 348 kJ/mol. What wavelength ( in nm) of light is required to provide sufficient energy to break the C-C bond?

To test satellites for durability, NASA simulates exposure to solar radiation using low energy x-rays. The two x-rays used have energies of 1.10 X 10-17 J and 3.04 X 10-16 J each (per photon). E2 The most strongly bound electron anywhere in these three elements is in Fluorine, with an ionization energy of 85,000 kJ/mol. Will this electron be removed by either of the x-rays?
Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in...
Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the...
