Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

Questions [1] One difference between mechanical waves and EM waves is: only one needs a source, only one needs a medium to disturb. (2) If a color of visible light had a frequency of 621 THz, then the color is: red, orange, yellow, green, blue, violet.

An octahedral metal complex absorbs light with wavelength 580 nm. a. What is the crystal field splitting A, in kJ/mol for the complex? (Hint: Energy is based on wavelength of light absorbed. See data sheet.) (3 marks) b. What color does the complex appear to the eye? (2 marks) 750 nm, 400 nm Red Violet 630 nm 430 nm Blue Orange 590 nm 480 nm Yellow Green 560 nm

3. [5] Retinal consists of a chain of carbon atoms roughly 1.5 nm long. Electrons in this long chain molecule behave very much like particles in a box The retinal molecule is a linear molecule that has 12 electrons that are free to move about the chain According to the Pauli exclusion principle, when this molecule is in its ground state, these 12 electrons fill the first 6 states of the box. Thus, the lowest energy photon that can be...

The illustration shows the
spectrum of electromagnetic radiation emitted by a blackbody at two
different Kelvin temperatures. The range of visible frequencies
(those that can be detected by the human eye) is also shown. (a) No
matter what the value of the Kelvin temperature T, the spectrum
decreases to zero at very high frequencies. Why is this? (i) At
very high frequencies the photon energy is very small compared to
kT. (ii) At very high frequencies the photon energy is...
