how are prisms and pyramids alike and how are they different?
97913
Pyramids have one base and lateral faces that are triangles where prisms have two congruent bases and lateral faces that are parallelograms.

The volume of the pyramid is 1/3 the volume of the prism.\n\nTo prove this, look at a horizontal cross section of pyramid. Let A = the area of the base.\n\n\nIf the the height of the pyramid is h, look at a cross section of the pyramid at a height t above the base. Any one dimentional measurement x in the base, will have size x(h-t)/n in the cross section. Any two dimensional measurement, (area) will be multiplied by ((h-t)/h)^2, i.e. A((h-t)/h)^2.\n\nNote\nNow integrate for t = 0 to h, A((h-t)/h)^2 dt\n\nYou get -A/3(h - t )^3/h^2.\nEvaluating at t = 0 and t = h you get 1/3Ah.\n\nThe volume of the prism is Ah.

I'm not entirely sure to what it is you're referring.  Most Egyptian pyramids are built of stone blocks or slabs - roughly dressed on the interior and smoothed on the exterior.  Typically the stone is limestone for the exterior, with the occasional use of granite on lower courses.  Interior chambers in the pyramid itself or subterranean chambers were frequently lined with a different type of stone - granite was a popular choice.\n\nThe peaks of the larger (ie. royal) pyramids are now large flat spaces now that stone has been robbed out and the pyramidia (capstones) have been removed.  The capstones, from what we know from contemporary inscriptions and a few examples that have actually been found were essentially little pyramids in miniature, each face was inscribed with the name of the pyramid  - each royal pyramid was named, usually a name including the nomen and/or prenomen of the king for whom it was built.  Additional inscriptions usually concerned the sun god and/or were specific to the cardinal direction that face of the pyramid faced.\n\nIt is extraordinarily unlikely that Egyptian pyramids serve as radio receivers and even more unlikely that they were designed to do so.  They were tombs.

a pyramid. 3 sides and the bottom is 4 sides. but only 3 corners.

THERE ARE NO PYRAMIDS ON MARS it is an optical effect caused by shadows also if the aliens built the ones on mars 7000,000 years ago they would not line up exactly with the ones on earth as the earth is constantly shifting and even 10,000 years of movement would put them out by at least a meter.

Prism works by refraction. As light goes through, different wavelengths? or frequencies (forgot which) are split of slightly so the light comes out of the prism at different angles. Thus the colors are split up.\nAs i remember, daimond is the best stuff for a prism. Highest index of refraction.\nDunno bout diffraction and depletion.\nLight refraction is when light goes through a substance and is bent to find the shortest way through the substance. (like when you look through a glass of water with a straw in it).

Different wavelength (colour) of Light when passed through prism refract (bend) by diferent angles...\nWhen red light is passed .. as it is composed by only on single wavelength, it, as a whole, bends by the same angle..\nSo, there will be a deviation, but no spliiting....\n\nWhite light has many colours super imposed ( made of many wavelength) and hence each component bends by diferent angles ... causing \nwhat is called, Dispersion.of white light

This is actually a fascinating question, so I'm going to give a long answer.  The short answer is "Nothing.  Nothing is similar."  Here's the long asnwer:\n\nTo the average user, it seems like there are a lot of similarities: \n\nthey both have memory, \nthey both take in information and put out information, \nthey both need sources of power\nThey both "think," sort of\n\nBut really, these are only similarities on the surface.  Although both you and your computer have memory, there are vast differences in how memory works, to the point where using the same word for the two types of memory is misleading.  While both you and the computer "think," how you do so is vastly different.  You work in patterns, the computer works in digital representations, which is more precise but far less efficient.\n\nComputers are phenominally fast calculators, but that's all.  They can add, subtract, multiply, divide, and move information around.  And nothing else.  I'm a programmer, trust me on this.  Everything they do is based on those basic operations.  Playing a video game is just basic math done incredibly fast.  Displaying an e-mail is just basic math on memory addresses and moving a block of numbers (representing the letters) from one location to another, where it can be turned into pixels (complicated math, but math none the less) and moving the results to specific memory ports where the electronic adapter turns the numbers into colors on the screen.  Computers seem "smart" because they're wickedly fast at processing numbers.\n\nYou, on the other hand, do poorly at numbers.  (And by 'you', of course, I mean humans.  But you knew that).  The fastest human savants calculate thousands of times slower than the computer in your microwave oven.  \n\nYou have advantages, though.  Your brain is a phenominal pattern matcher.  Your pattern matching abilities exceed anything any computer can achieve.  For example, if I scrawl the word "Howdy there!" on a piece of paper and hand it to you, you'd instantly know what it said, even if I was a wee bit sloppy with the letters or gave it to you upside-down.  The letters (and even the words) are patterns you've seen before and can immediately interpret them.  A computer would have to analyze it pixel-by-pixel and MIGHT be able to interpret the letters eventually.  But in all probability, the computer is going to have trouble figuring out where the lines start and stop, and which line goes with which line in the text.  Character recognition is a tricky thing for a computer... and if you give it the text upside-down it'll never figure it out.  \n\nEven a six-month-old baby is better at recognizing different faces than the best computer program running on the fastest computer that Homeland Security has.  And trust, me, they're working on improving that so they can recognize bad guys from security cameras.  \n\nNow we get back to memory and how vastly different they are.  A week from now, you'll remember that the paper said "howdy there!" and may or may not remember vaguely whether the handwriting was neat or sloppy.  This is because your memory stores the pattern.  The computer, however, could give an exact reproduction.\n\nStudies have been done with what types of things people remember.  When flashed briefly with an image of a cluttered desk, for example, and then asked to write down what was on the desk, people tend to remember the things that are out of place (a shoe, a tennis ball) and not remember things that were expected there (a stapler, a cofee mug).  This is because that powerful pattern matcher in your head evaluates the pattern (an office desk) and notes anything that doesn't match.  Your memory doesn't need to store typical desk items as much as it does exceptions.  It's very efficient that way.  You filter out the "ordinary" and spend almost no time thinking about the

Well the white light is a mixture of a large number of wavelengths of lights. These different wavelengths of lights travell at different speed in the medium such as glass. In air and vacuum the have alsmost the same speed. But in prism the travell with t&#92;different speeds. So when the pass prism the length of path travelled in the same times is different and hence when the emerge out, the different colrs are at differemt positions resulting in a seperation of colours.\n    This is called the dispersion of light.

Your eyedoctor is right. A prism is shaped like a triangle.On one end is the base and at the other end is a point. This is put in a optical lens to deviate the light.\n\nIn some hard contact lens a ballast can be put to keep it position. A ballast is like a prism but it is not used to deviate light like in a prescription lens.
