Methodology of kaleidoscope ​

Answer»

KaleidoscopeThe kaleidoscope makes magic with light and mirrors. It may be considered a child's toy (or a toy for all ages), but it is ALSO a simple optical device with technical APPLICATIONS for designers and pattern-makers. Greek words are the source of the name; it comes from kalos, eidos, and skopios meaning beautiful, form, and view, respectively.BackgroundThe body of the kaleidoscope has two main parts, the viewing tube (with an eyepiece at ONE end) and the object box or CASE at the opposite end of the tube. The object box is a thin, flat box made of two glass disks and a band circling the edges and holding the disks and the objects enclosed. Those objects are fragments of colored glass, beads, tinsel, or other reflective materials.The outer disk of the object box is ground so it diffuses the incoming light; that is, it acts like a screen. The viewing tube has a glass eyepiece at one end; it may be ordinary glass or an optical lense with magnifying properties. Inside the tube, three strips of mirrors are JOINED to form a triangle; the angles of the mirrors also affects the view through the kaleidoscope. Typically, they are angled at either 45° or 60°. When the object box is turned or tapped, the glass or objects inside move and tumble freely. As the viewer looks through the eyepiece toward a light source, the mirrors produce symmetrical order out of the tumbling objects and multiply them six, eight, or more times depending on the angles of the mirrors.A variation of the kaleidoscope—the teleidoscope—replaces the object box with another lens that allows the viewer to look at a distant object and view it in multiples. Still other variations use more mirrors. Two mirrors have the advantage of producing a centered pattern; multiple mirrors split and duplicate the image many times over. The kaleidoscope is infinitely entertaining because the patterns and combinations are endless and are not permanent unless photographed.HistoryAlthough the ancient Greeks, including the mathematician Ptolemy, had contemplated the effects of abutting multiple mirrors, the kaleidoscope is the creation of one man. David Brewster (1781-1868) was born in Scotland and educated to become a minister at the University of Edinburgh. University studies exposed him to the wonders of science, however, and he abandoned the church in favor of studying the properties of light. He became an expert in polarization of light (the linear and planar properties of light), reflection of light using metal, and light absorption. For his scientific discoveries, Brewster was elected a fellow of the Royal Society (Britain's leading scientific organization) in 1815 and knighted in 1831.Brewster invented and patented the kaleidoscope in 1816. He described its structure and operations in a 174-page scientific paper titled Treatise on the Kaleidoscope. In his treatise, Brewster calculated that 24 fragments of glass in the object box of a kaleidoscope could create more than 1.4 x 1033 fleeting views. He also described the most effective combinations of colors for kaleidoscopes based on light properties. In the 1840s, he used two lenses to produce a three-dimensional effect in creating the stereoscope. He was also a leading advocate of the flat Fresnel lens adopted by the British for lighthouses and was credited with saving thousands of lives by protecting vessels against shipwrecks. Brewster taught at the University of Edinburgh and the University of St. Andrews in Scotland, was one of the first editors of the Encyclopedia Britannica, and published many books and scientific papers.Explanation:

B) How do you tone your radio set to a particular station? Name the phenomenon involve in doing so and define it.​

Answer»

The phenomenon involved in tuning a radio SET to a particular station is called resonance. Resonance : When the frequency of an EXTERNALLY applied periodic FORCE on a body is equal to its natural frequency, the body readily begins to vibrate with an increased amplitude. This phenomenon is known as resonance. Loudness is the PROPERTY by virtue of which a loud sound can be distinguished from a faint one, both having the same pitch and quality. Hope this helps.

Is the change in the atmospheric pressure uniform in part?

Answer»

NOExplanation:The DECREASE in ATMOSPHERIC pressure with gain in altitude is not uniform. Although the height of the air column decreases uniformly with accent, the decrease in DENSITY of air is not uniform. The decrease in density of air is rapid in relatively low ALTITUDES and is slow in the upper layers of the atmosphere.

Opinion about kaleidoscope​

Answer»

Explanation:A kaleidoscope (/kəˈlaɪdəskoʊp/) is an optical INSTRUMENT with two or more reflecting surfaces tilted to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection.It was thought that the PATENT was reduced in a Court of Law since its principles were supposedly already known. Brewster stated that the kaleidoscope was different because the PARTICULAR positions of the object and of the eye, played a very IMPORTANT role in producing the beautiful symmetrical forms.

An object weighing 400N on the surface of earth. At what height from the surface of earth it's weight will become 100N?

Answer»

5.16 x 10^6 m = 5160000 m EXPLANATION: Let x metres be that height from the SURFACE Weight on the surface = 400N=> mass of the object = 40 kg ( TAKING g = 10 m/s^2 at the surface) 100 = GMm/x^2=> x^2 = 6.67 x 10^-11 x 10^24 x 40 /100=> x^2 = 6.67 x 10^12 x 4=> x^2 = 26.68 x 10^12=> x = root of 26.68 x 10^12=> x = 5.16 x 10^6 m.

A car travels a distance of 900 m with 30 m/s and next 400 m with 20 m/s along a straight road. The average speed of the car will be A. 26 m/s B. 14 m/s C. 28 m/s D. 42 m/s

Answer»

A) 26 m/sExplanation:Average SPEED  = total distance travelld / total time taken time taken to travel 900 at 30 m/s is time = distance / speed = 900/30 = 30 sectime taken to travel 400 at 20 m/s is time = distance / speed = 400/20 = 20 sechence average speed is = (900+400)/(30+20)=1300/50=26 m/sanswer is option A) 26 m/s

characteristics of convex mirror , concave mirror , convex lens , concave lens , plabe mirror for class 7​

Answer»

Concave MIRRORS can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can ALSO be enlarged, reduced, or the same size as object.Convex mirrors reflect light outwards (diverging light rays) and therefore they are not used to focus light. The image is virtual, erect and smaller in size than the object, but gets larger (maximum upto the size of the object) as the object COMES towards the mirror.convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. ... Both diverge parallel rays away from a focal point, have negative focal lengths, and form only virtual, smaller images.concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (MYOPIA)plane mirrors produce images with a number of distinguishable characteristics. Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.

Imagine what happens if chemical bond does not form

Answer» TION:A chemical reaction can only TAKE place upon the breaking and formation of new chemical bonds. Chemical REACTIONS are irreversible reactions, yet they need some excitation energies for the reactions to take place. Also for the reaction to be stable, it is important that there is enough chemical bondage AMONG the NEWLY formed molecules. The stronger the bondage the more energy will be required to break it
