collecting process was done, the apparatus was removed from the heat. The odors of obtained ester and hood partner’s ester were examined. The percent yield of crude and distilled product were calculated. A sample of the product was placed into an infrared spectrometer to generate a visual representation of energy bands given off by the compound that signify functional groups in the product. The appearance of certain bands helps to identify the composition of the compound present. To clean up,…

Since Mars is much distant from Earth, observations are done through the use of thermal infrared spectroscopy of THEMIS and Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) which aboard the Mars Reconnaissance Orbiter (Wray et al., 2013, 1013). CRISM absorbs infrared wavelengths that reflect on the planet’s surface detecting rock compositions. Although Mars was said to have no felsic rock formation, CRISM detected areas…

which, 70% is initially absorbed by the Earth’s surface. However, as the earth warms, some of this absorbed energy is reflected back toward space as infrared radiation. This infrared radiation would be lost into space except for the fact that there exist greenhouse gases such as carbon dioxide and water vapor in the atmosphere that absorb the infrared radiation and sends some of it back to Earth’s surface, keeping Earth at a temperature that can support life. This is all well and good but human…

They are all simply electromagnetic radiation of different wavelengths. For fiber optics with glass fibers, infrared light is used for fiber optics because it contains wavelengths longer than visble light, which is around 850 to 1150 nm. (As seen on the diagram) Infrared is used in fiber optics because the amount of data loss of the fiber is much less at infrared wavelengths, loss of data in glass fiber optic cables is caused by two factors, absortion and scattering. Absortion occurs…

In this lab, the objective is to research astronomical devices through the provided respective links. After choosing one of the devices used to study Astronomy, the researcher must then begin to delve into information about the device and its current location and providers. Through research an understanding is gained, and the researcher is able to better comprehend the capabilities of their decided to device. Once this step is achieved, it is next part of the process to review images produce by…

Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…

method for separating the 100 % agave tequilas from the mixed ones. The purpose of this study was to examine the composition of various samples of authentic tequila purchased in Mexico and Germany using ion chromatography (IC) and Fourier transform infrared (FTIR) spectroscopy. It was expected…

In 2004, a servicing mission is called once again for concerned safety on the fails of shuttles. The investigation starts for some telescopes that require longer work. 2005, the infrared cameras pass initiation. Also during this year, Hubble captures two images of moons orbiting Pluto. During 2006, another servicing mission is called, servicing mission 4. All of Hubble’s designs are successful and able to be initiated. Throughout…

We’re currently in the technology era, with new things being developed and discovered almost every day. Something crazy is always in the works and the next big technology always seems to be right around the corner. Self-driving cars and iPhones aside, some of the biggest advancements are happening in the industry of space exploration and physics. SpaceX just recently landed a launched rocket safely onto a barge out in the ocean, LIGO discovered that Einstein’s predicted gravitational waves are…

such as it only really allows detection of larger e.g. the size of Jupiter. The smaller the object the harder it gets it is to pick out against its parent star. Other methods included in this category is infrared imaging which is used much more than the first method because it can see into the infrared spectrum, this only works if they are very hot planets. The next lot of methods come under a different category of they are called indirect methods these in some case do not need line of sight on…
