Answer #1

b. Quantum theory supports discrete energy differences

when an atom is supplied with a sufficient amount of energy the electrons can absorb that energy and move to a higher energy
level the energy levels of the electrons in atoms are quantized an atom cannot absorb an unspecified
amount of energy it can only do so in amounts that are equal to the difference between two allowed
energy levels one .when an electrons enter into higher energy to lower energy . The emision spectrum is formed

1. Why might a stream of red photons not cause an electron to be emitted from a gold surface? A. The stream of red photons might not be hitting the surface with enough total energy per second B. An electron absorbs the energy of one photon, and the red photon has too small of a wavelength to deliver enough energy. C. An electron absorbs the energy of one photon, and the red photon has too small of a frequency to...

Which of the following is the best explanation for why rod-based vision does not support the perception of different hues (or colours)? A. Dark Current: Rods only generate action potentials in the dark, so really code the absence of light. This makes colour vision impossible using these photoreceptors. B. The Principle of Univariance: Variations in both the wavelength and intensity of light result in variation of response in the rod-based system. Because the response from ganglion cells is univariate, both...
