List the two wavelengths of light that are NOT absorbed by the Earth’s atmosphere. Of the two name which is impervious to the atmosphere so there is no reason to observe above it. Concerning the other one, why is it still useful to place the telescope above the atmosphere if this wavelength is not absorbed?

1. Atoms can only emit certain wavelengths of light because a) not every color actually exists in nature. b) light is made of discrete particles called photons. c) their electrons are limited to discrete energies. d) All atoms can emit continuous spectra. 2. How many red photons, with wavelength of 650 nm, does it take to equal the energy of a single 6.5 nm x-ray photon? 3. In a photoelectric effect experiment, light with frequency below the sample's cut-off frequency...

Many organic molecules that absorb light in the visible range possess molecular structures with extensive conjugation. With reference to molecular electronic orbitals and their relative energies, briefly summarize how the degree of conjugation within a molecule affects the UV-vis absorption spectrum.

Which of the following best explains what happens as photons of visible light are absorbed by dye molecules?

Which of the following best explains what happens as photons of visible light are absorbed by dye molecules? A. Certain electrons in the dye molecule move to a higher energy level, with the difference in energy between the lower and higher energy levels being the same as the energy of the absorbed photons B. Certain chemical bonds in the dye molecules begin to bend and stretch with the difference in energy between the lower and higher vibrational states being the...

aWhat wavelengths of light worked best for the production of oxygen? Hypothesize why it was those particular wavelengths of light that produced the most oxygen.b)Why did using the full spectrum of light work best for the production of oxygen?c)Explain why an increase in carbon dioxide in the Habitation Unit would not result in greater production of oxygen. Your explanation should include a discussion on the light-dependent reactions and the Calvin cycle.d)Explain why a change in pH did not have an...
