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...
The horsefly Hybomitra lasiophthalma has a cuticle that is made up of a layer of chitin 89 nm think with an index of refraction of 1.73. This layer is on top of chitin with a smaller index of refraction (1.40). When light shines on the cuticle with an angle of incidence of 0o, what color will the cuticle appear? You may assume that the horsefly is in air. Explain/show your work. *Color wavelength (nm) Purple 380-450 blue 450-495 green 495-570...

State the null and alternative hypotheses. It has been rumored that the color distribution of M&M’s is 30% brown, 20% yellow, 20% red, 10% orange, 10% blue, and 10% green. You suspect this rumor is incorrect and decide to count how many of each color are contained in a randomly chosen bag in order to perform a Chi-Square goodness-of-fit test at a 5% significance level.
