[pic] An optical illusion also called a visual illusion is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them‚ physiological ones that are the effects on the eyes and brain of excessive stimulation

The telescope is an important astronomical tool that gathers and focuses electromagnetic radiation. Telescopes serve to both increase the angular size and the brightness of objects. When we speak about telescopes we are usually referring to optical telescopes‚ but many other types of telescopes also exist for other spectrum of electromagnetic radiation. It is unclear as to who it was that actually invented the telescope but Galileo Galilei is credited as being the first to use a telescope for

Dietary Fiber Dietary Fiber is the parts of plant that resist digestive enzymes. A few definitions of dietary fibers are nondigestible carbohydrates and lignin that are intrinsic and intact in plants. nondigestible carbohydrates and lignin that are intact in plants. Another definition is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine‚ with complete or partial fermentation in the large intestine.

Global Fiber Optic Sensor Market 2015-2019 rd On 3 Jan 2014 About Spectrum Analyzers A fiber optic sensor is a device that employs optical fiber technology to transmit signals to amplifiers for processing. Qualities such as distributed sensing‚ the ability to withstand high voltage‚ and critical environment conditions help end-users improve the quality of operations and save costs. These benefits have increased the adoption of fiber optic sensors across industries such as Oil and Gas (for drilling

he recommended fiber intake is 20 - 35 grams per day for adults‚ or 10 - 13 grams for every 1‚000 calories in the diet. This recommended amount should come from a combination of soluble and insoluble fiber‚ since each type provides different benefits. While it’s not necessary to track‚ a 3:1 ratio of insoluble to soluble fiber is typical. Although neither type is absorbed by the body‚ they have different properties when mixed with water‚ hence the designation between the two. However‚ due to

Dietary fiber is several plant materials that the body is unable to digest. Fiber is important for the digestive system and lowering cholesterol. Fiber is divided into two categories: soluble and insoluble. Soluble fiber can dissolve in water which forms a gel-like substance. Soluble fiber has been connected with increased diet quality and a decrease in the risk of cardiovascular diseases. Some foods that are high in soluble fiber include: oatmeal‚ legumes‚ strawberries‚ apples and barley. Insoluble

The function of fiber in the body is to help with gastrointestinal health and cholesterol-lowering benefits. Fiber is also an important role in seven other essential nutrients that the body needs to have. Some food sources of dietary fiber are wheat‚ rye‚ oats‚ beans‚ peas are some of the main foods that provide good fiber that can benefit people. Fruits and vegetables are better sources of fiber‚ but people would have to eat more of these foods in order to equal the fiber contributions of beans

Optical illusions are all around us(explain). The brain remembers what it has seen before‚ then when it sees something similar it takes shortcuts when looking at a new images. This causes the brain to make mistakes and creates optical illusions. An optical illusion is a misleading image that deceives the eye. Different people see optical illusions differently because of their previous experiences. Previous experiences help the brain interpret what it sees. If your previous experiences determine

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)
