Homework Answers
The perceived color of the pigment depends upon the wavelengths of light that are not absorbed. So from the given absorption spectrum of the pigment, we can see that the pigment absorbs blue color the least. So most probably the pigment will be of blue color.

The electronic absorption spectrum UI (Cr(NH3)6]3+ (aq) is shown in Figure 11.5. One of the observed peaks is centered at about 303 nm. 1.a. What is the approximate value of the wavelength for the two other peaks? Which one of these three peaks falls in the visible region of the electromagnetic spectrum? The wavelength at this peak is (Amax), and this transition accounts for the color of the complex ion in solution. The energy of the transition occurring at...

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...
