Oil Painting The oil painting technique traces its roots all the way back to a time between the fifth and ninth century when it was first used in Western Afghanistan‚ yet it was made famous and the premier means of expression by the Renaissance movement in the 15th century by men like Leonardo Da Vinci and Raphael (Davide 46). The reason the oil painting technique gained this newfound popularity was due in large part to its ability to convey things such as human flesh more accurately while also

Sample Lab Report for CHM 152 Name Lab Partner(s) Abstract: The physical properties‚ including the boiling point‚ density‚ and refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical

wavelength range of 4000–650 cm–1‚ at a spectral resolution of 4 cm–1 over 32 scans. In attenuated total reflectance (ATR) spectroscopy‚ the sample is placed in contact with a special crystal which is composed of a material with a high index of refraction [e.g.‚ zinc selenide (ZnSe)‚ thallium bromide iodide (KRS-5)‚ Ge]. Figure 6 shows FTIR–ATR spectrum extracted from the imaging of the green paint sample. Mineralogical species of green earths can be distinguished in the 3400–3700 cm−1 and 950–1100

Did you get it? 1. What’s the role of eyelids? To protect the eyes. 2. Which structure of eye forms tears? Lacrimal glands 3. What are tears? A dilute saline solution containing lysozyme and antibodies. 4. What’s the visual role of the external eye muscles? They direct the eyeball toward what you wish to see. 5. What is the meaning of the term blind spot in relation to the eye? The blind spot contains no photoreceptors; it is the site where the optic nerve leaves the eyeball 6. What function

Sir Isaac Newton was born at on January 4th (December 25th old calendar) at Woolsthorpe‚ a farmstead‚ in Lincolnshire. Woolsthorpe is the place where he worked on his theory of light and optics. This is also believed to be the site where Newton observed an apple fall

in beings‚ besides being the sole component of diamond‚ graphite and coal. Diamonds are fascinating. They are chemically resistant and it is the hardest natural known substance. Diamonds also have special optical properties such as high index refraction‚ high dispersion and high luster. Four processes are thought to be responsible for virtually all of the natural diamonds that have been found at or near Earth ’s surface. One of these processes accounts for nearly 100% of all diamonds that have
