What are diffraction glasses?
Diffraction glasses differ from traditional glasses because they use a special pair of lenses that offer light grating as an entertainment source. When viewing a light source the grating effect will break the light into a prism of colors, offering the user a unique experience. You can check out companies like GloFX to view the various glasses that will feature this special lens. They also have a great FAQ page about diffraction glasses, you can read up on it by searching GloFX Glasses What Are Diffraction Glasses.

What causesan accumulation of excess fluid in the pericardial space?
Pericardial effusion is the medical term meaning abnormal accumulation of fluid in the pericardial space. If the fluid affects the function of the heart, it's called cardiac tamponade. When this sac becomes filled with fluid, the liquid presses on the heart, preventing the lower chambers of the heart from properly filling with blood.
What are some terms and jargon used by chefs and cooks?
Mise en place - means to get everything ready before you start cooking Sauté - means to fry quickly in a little hot fat Roux - half butter, half flour, gently cooked and used to thicken a white sauce Mirepoix - means a combination of onions, carrots and celery, gently fried and used as a base for a soup or sauce. Commie Chef - Junior most Chef, usually a trainee just starting a new career. Rombaux - A 10 inch bladed heavy knife, used to chop roasted chicken or duck in half, each portion having a leg and a breast. Mandoline - A manual slicing, chopping and grating set with interchangeable stainless steel blades normally used to prepare vegtables. al dente - a term that describes pasta which has been cooked so as to be firm but not soft, it's said to still have a 'bite'
What are the early signs of osteoarthritis?
What is Osteoarthritis Osteoarthritis (OA) is one of the most wide spread types of arthritis and is found most often to stast developing after the age of 45. I may also form as the result of a jury to a joint. Men and women are affected equally by this condition.AO causes the breakdown of the cartilage between the joints. Cartilage is the material that covers the end of the bone at the joints to ensure smooth and effortless movement. In OA, this cartilage breaks down.OA usually occurs in the fingers and weight-bearing joints; these include, knees, feet, hips and back. Osteoarthritis is the result of changes in the cells of the cartilage resulting in a loss of elasticity. Over time this causes the cartilage to thin out and in some situation breakdown all together. This leaves the ends of the bone without its smooth covering, and the joint loses its easy mobility.. OA progresses slowly. For many people the symptoms will be mild and have little impact. OA rarely causes severe disability, but when it does surgery to replace joints is often highly effective. Symptoms of OA vary. Most individuals remain essentially free of symptoms until the cartilage ceases to function properly. After that they may include, Pain, Swelling, and stiffness in the affected joint or joints. To diagnose RA Your doctor will first assess your situation by checking the affected joints for outward signs of inflammation heat etc. then if he deems it necessary may order tests such as X-ray and blood tests joint fluid tests to exclude the possibility of other types of arthritis.The management of this condition depends on the joints affected and the physique of the patient. And includes, Exercise, Education, Medication, Joint protection, and Healthy weight maintenance Answer also: "Osteoarthritis", states the Western Journal of Medicine, "is in many ways like the weather, ubiquitous, often unnoticed, sometimes dramatic in its effects. OA concentrates its erosive influence in one or just a few joints. As cartilage is slowly eroded, bone begins to grinding against bone. This is accompanied by an outgrowths caused osteophytes. Cysts may form, and the underlying bone thickens and become deformed. Other symptoms include knobby knuckles, grating and grinding sounds that emanate from arthritic joints, and muscle spasms, along with pain, stiffness and loss of mobility. The American Journal of Medicine states: There is no evidence that a normal joint, subject to common stresses, will break down over the life of a person. Efforts to understand the exact cause of OA are "plagued by controversy" according to the British magazine The Lancet. Some investigators propose that damage to a bone, such as micro-fractures may occur first. This, in turn may trigger bony outgrowths and cartilage deterioration. Others think that OA starts in the cartilage itself. As it degenerates and frays, they reason, stress increases on the underlying bone. Pathological changes occur as the body attempts to repair the damaged cartilage. While age doe not cause OA, the loss of joint cartilage experienced more frequently with increasing age. Other risks may include those who have an abnormality in the way their joint surfaces fit together or who have weak leg and thigh muscles, legs of unequal length, or a misalignment of the spine. Trauma to a joint caused by an accident or by an occupation in which repetitive motions overuse a joint can also set the stage for osteoarthritis. Once deterioration begins, being overweight can exacerbate OA.
Is diffraction grating is used in polarization?
No diffraction grating is not used in polarization.
What is diffreance between transmission grating and diffraction grating?
Diffraction gratings can be categorized into 2 types - reflection gratings and transmission gratings. So, transmission gratings are a subset of diffraction gratings. Kristian Buchwald, Ibsen Photonics
What is the difference between dispersive and resolving power of diffraction grating?
The ability of an optical instrument expressed in numerical measure to resolve the image of two nearby points is termed as resolving power. The dispersive power of a diffraction grating is defined as the rate of change of the angle of diffraction with the wavelength of lite. S M SOHEL RANA IU
Why does a diffraction grating will separate while light into colors?
A diffraction grating does not disperse light into its component colors. However, a prism does. A diffraction grating simply causes light to diffract and display an interference pattern on a screen.
What is the grating constant for a 600 lines per mm diffraction grating?
1.667
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
for diffraction grating mercury lamp is used not sodium lamp.
Where to buy diffraction grating?
Try Edmund Scientific
What can a diffraction grating be used for?
measuring wavelengths of light
Role of the diffraction grating in the spectroscope?
spectroscope and its roles
How diffraction grating could be used as the dispersive element?
Diffraction grating could be used as the dispersive element because of the ability of light to be broken according to various wavelength.
What kind of pattern of light would you get if you shone monochromatic light on a diffraction grating?
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
What is a diffraction grating?
A diffraction Grating is an array of arranged lines, normally a wavelength apart. They are commonly used to measure the size of your penis because its so small it has to be measured in nanometers.
