Wavelength

Planets and moons within the solar system are different in terms of composition, geologic activity, interior structure, magnetic field, and atmospheres. We can deduce each of these properties through routine astronomical observations, spectroscopic/remote observations, laws of physics, solar system modeling as well as direct sampling. Given that many economists and government officials object to using our resources to visit other objects physically, by studying our solar system we will continue…

Within the article this term is used to describe light as heat. Particularly, body heat released by the body, which is “7- to-14-µm on the wavelength range (Torrice).” This wavelength range comes from the Electromagnetic Radiation Spectrum on pages thirty to thirty-one of the “CHM 110 Required Note Packet.” This chart shows a spectrum from gamma rays to radio waves. Gamma rays, in which, are high energy radiation…

Since all of the different types of electromagnetic waves travel at the same speed (~3x108 m/s), the only factor to change is the wavelength (λ) or its inverse, the frequency (μ). To acquire this value, the ideas of electromagnetic and cosmic radiation have to be accounted for. Because all objects in our universe and anything between us and the receiving planet emit some sort of electromagnetic…

electromagnetic spectrum. This region is light with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can absorb infrared radiation and convert it into heat. (Cole) A machine called an infrared spectrometer applies infrared rays to a substance to record the number of wavelengths absorbed by said substance. (Cole) This works…

which color was being absorbed and reflected. There were two peaks, where the two colors were being the most absorbed. Once the absorbance was figured out, the food dyes that is needed in the Gatorade was present by using the color spectrum and the wavelength. These colors were green (514 nm) and orange (629.6 nm). Then the emitting colors can be solved. The colors that were emitted were red and blue. So, the food color dyes that was needed was FD&C Blue #1 and FD&C Red #40. To determine the…

Light as a Pesticide What is a pesticide? Pesticides are substances which are used for attracting and then destroying or vindicating any kind of pests. It is a biological agent which is used to destroy pests. Pesticides are usually used for keeping pests away from plants. Pesticides are used fight insect-borne diseases and they also help to increase food production. Although pests have numerous benefits they also have few drawbacks such as possible toxicity to humans and other species. What is…

During this experiment that was conducted in partners, the concentration of RNase H that was purified in the previous experiment #6 was determined and also the concentration of an unknown given solution using their absorbance values obtained from the spectroscopy apparatus. These concentrations were calculated using the equation of the line produce with the values of the concentration (x-axis) and corresponding absorbance (y-axis) of five protein bovine gamma globulin standard solutions. In…

reflected not absorbed. The darkness also presented zero floating leaves and this is due to the fact that no light would mean that there was no energy source for photosynthesis to occur. The second highest was red and this is due to being a bigger wavelength than blue which also had some floating leaves. The reasoning behind the floating of the leaves is that there is a photosynthetic reaction occurring which produces oxygen in the deoxygenized leaves making them float. (Osterhoudt) The leaves…

There are two basic types of fireworks that form the big displays in the sky: firecrackers and sparklers. They are made in different ways. Firecrackers are rolled paper tubes that are filled with gunpowder called black powder or a fuse and flash paper. As you light the fuse, fire burns along the fuse and when it reaches the powder there is a loud explosion. Sparklers, though, make colorful, long lasting light. They contain more ingredients which means they burn longer and produce a light and…

Defining healthy sun exposure and sunscreen’s role Most cancer rates are decreasing, whereas skin cancer continues to steadily increase as it has for the past decades (Saraiya et al. 422). The three most common skin cancers are squamous-cell, basal-cell and melanoma carcinomas. Squamous-cell and basal-cell carcinomas are grouped as non-melanoma cancers. Family history and genetic disorders increases the risk of forming cancer; however, estimates place excessive sun exposure as causing as much…
