can anyone give me the method for making a simple telescope as well as a microscope?

Make a Simple Telescope\nYou will need the following: \ntwo magnifying glasses - perhaps 1 - 1.5 inches (2.5-3 cm) diameter (it works best if one is larger than the other) \na cardboard tube - paper towel roll or gift-wrapping paper roll (it helps if it is long) \nduct tape \nscissors \na ruler, yard stick, or tape measure \nsheet of printed paper - newspaper or magazine will do \nTo assemble your telescope, do the following: \nGet the two magnifying glasses and a sheet of printed paper. \nHold one magnifying glass (the bigger one) between you and the paper. The image of the print will look blurry. \nPlace the second magnifying glass between your eye and the first magnifying glass. \nMove the second glass forward or backward until the print comes into sharp focus. You will notice that the print appears larger and upside down. \nHave a friend measure the distance between the two magnifying glasses and write the distance down. \nCut a slot in the cardboard tube near the front opening about an inch (2.5 cm) away. Do not cut all the way through the tube. The slot should be able to hold the large magnifying glass. \nCut a second slot in the tube the same distance from the first slot as your friend wrote down. This is where the second magnifying glass will go. \nPlace the two magnifying glasses in their slots (big one at front, little one at back) and tape them in with the duct tape \nLeave about 0.5 - 1 inch (1 - 2 cm) of tube behind the small magnifying glass and cut off any excess tube remaining. \nCheck to see that it works by looking at the printed page. You may have to play slightly to get the exact distances between the two glasses right so that the image comes to a focus. \nWith your telescope, you should be able to see the moon and some star clusters as well as birds, etc. \n\n+++++++++++++++++++++++\n\nMake a Simple Microscope\nYou can make a simple microscope by using magnifying glasses and paper: \nGet two magnifying glasses and a sheet of printed paper. \nHold one magnifying glass a short distance above the paper. The image of the print will look a little bit larger. \nPlace the second magnifying glass between your eye and the first magnifying glass. \nMove the second glass up or down until the print comes into sharp focus. You will notice that the print appears larger than it does in the first magnifying glass. \n\nI've included two links below for this and other info.\n\nMyst

Hi. You could start here : http://www.mellesgriot.com/products/optics/oc_3.htm\nMay not be the best for everyone.

Try a Yahoo search for parts of a microscope\n\nFound several sites that look useful:\n\nAn online "flashcard" quiz to practice naming the parts:\n\nhttp://biologycorner.com/microquiz/\nhttp://www.cas.muohio.edu/~mbi-ws/microscopes/microscopeparts.html\n\n\nDiagrams with labels:\n\nhttp://www.usoe.k12.ut.us/curr/science/sciber00/7th/cells/sciber/micrpart.htm\nhttp://www.middleschoolscience.com/scope.htm

Here's some info to get you started. Good luck on your project.\n\nhttp://www.astronomy.com/asy/default.aspx?c=ps&id=6t/\n\nhttp://www.aboutastronomy.ne

You're talking about a Class 4 laser.  \n\nThis is more than you can do in a science project.  A laser like that would have high voltage and the light could easily blind you, and the components would be more expensive than you think.  The assembly and alignment is a very fussy procedure, and can't be done in a home workshop, due to the dust that's everywhere.  \n\nMaybe you could make a twyman-green interferometer, for measuring curvature of glass, but it won't be very dramatic.\n\nI figure that a motivated adult with some electronic and physics background, $50K, and a lot of time on his hands might be able to do it in a year.\n\nIf you're into optics, you can do some demonstrations with the beams from laser pointers....

ANYONE WITH A MICROSCOPE AND CAMERA

Well you would need light boxes, mirrors and prisms\n\nyou could ask them to do all the things to do with angles of light going through the prisms\n\nand you could ask them to build periscopes\n\nI can't remember my optics very well but if its possible then you could ask them to measure the magnification of the curved mirrors.

In general, the best money for the aperture (the amount of light the telescope takes in), is a Dobsonian-style Newtonian. They are significantly less expensive than refractors with the same light gathering power. As for brand, etc., as long as you get it at a place that sells primarily cameras/telescopes/binoculars, you should be fine. Avoid department store/Wal-Mart telescopes; they may be cheap, but that's what you get. The sources provide a lot more information.

Newtonian telescopes are especially easy to collimate, since there is only one curved mirror and an eyepiece.  Basically, you need to get the eyepiece centered in the image formed by the mirror, you have to get it pointed in the right direction, and you have to get it focussed.

Nice to see an Indian on here!! I'm an Indian too! Maharashtrian and mainly from Pune city. Yeah, you can get telescopes in India and the prices do vary dependent upon the power it has. An average telescope that can allow you to study the solar system in a glance is available at Rs. 7000. I saw one in an exhibiton, but sorry can't really specify where you can get it. Give me your mail id and if i find anyone selling it, I'll give you the whole details. why don't you make one?? that's a great idea, cause i have made one myself that is as cheap as Rs. 500!!

ok here is the thing\nif you are trying to calculate the thickness of a piece of paper you will need some equpment. Even though there is a lot of room for human error you still can get a fair estimate. \n\nwhat you need is 2 extrememly smooth glass plates and a lineat light source say a laser pointer. \n\nput one glass plate on a table place your paper on the side of the glass and put the other glass plate on the top of the two so that you will get a wedge between the two glasses. \n\nnow point the laser pointer perpendicular to the bottom glass plate and place a screen for reflections. you will get multiple reflections. (btw you need to know the frequency of the light emitted from the pointer.)\n\nthis is the set up\nfor calculations do a little search on air wedge interference \n\ni dont think you will need refractive indexes since you are using the same glass\nwith a little algebra you can figure it out

Yep, check out the Meade Telescope site.  Great new stuff in astronomy.

There's no one best telescope; it depends on what you want to do with the scope. How much you're willing to pay enters into it too - you can easily spend $100,000 or more if you want to.\n\nStarmaster ( http://www.starmastertelescopes.com/ ) makes excellent large dobsonians, available with computer control if you want. Or, a  Schmidt-Cassegrain (or the similar Meade RCX) makes a good general-purpose scope. \n\nAs uncertain as you are, you would benefit from some hands-on exposure to telescopes. Seek out your nearest astronomy club,  at http://skytonight.com/community/organizations and get to some star parties. One of the large regional star parties will expose you to a broad range of amateur equipment ( http://skytonight.com/news/3306276.html ).\n\nPermit requirements for an observatory will vary with the scope of your plans and local regulations. Generally, an observatory would be in a similar category to a small workshop.

Give this site a look.  And I think everything on it is under $300\n\nhttp://space.about.com/cs/telescopes/tp/tpbegscop300.htm\n\nGood luck.

Perhaps you mean "novice" as in beginner?\n\nThere are many resources out there for building a telescope. One place you might check is on www.atmsite.org\n\nThere are also many books on the matter under "Telescope Making"
