The spectral colors of the rainbow are caused by dispersive refraction. Newton established that refraction causes the dispersion of light into its constituent hues. He named seven colors, in symmetry with the seven distinct notes in the Western musical scale.t is the ratio of the speed of light in a vacuum (c) to the speed of light in this medium (v): n = c / v. The bending of a light as it crosses the boundary into a different medium is determined by its refractive index, or how much the light is slowed down in the new medium.
Brief Description. Opioids are a class of drugs that include the illegal drug heroin as well as powerful pain relievers available legally by prescription, such as oxycodone (OxyContinÂ®), hydrocodone (VicodinÂ®), codeine, morphine, fentanyl, and many others. These drugs are chemically related and interact with opioid receptors on nerve cells in the body and brain.
Genetic Name: Acetaminophen and Oxycodone. Percocet is the brand name for acetaminophen and oxycodone and is a powerful narcotic used to treat moderate to severe pain. The synthetic opioid is one of the most commonly prescribed painkillers. Percocet is available in capsules and tablets. Adults should not take more than 4 grams (4,000 mg) of acetaminophen in a 24-hour period as it can cause liver damage.
