TELESCOPES - LAB

Telescopes help people to see far objects closer or in more detail. Binoculars magnify distant objects and consist of two similar telescope, one for each eye to make viewing easy. They contain two prisms which make the image right side up. You will understand why you need to do this when you complete the lab. You will also be asked to determine if the image is just larger (magnification) or if the lenses create a better, more detailed picture (resolution). When you look through the lenses make sure that the image is in focus. You may have to move the lense back and forth to find the place of best focus. On the pictures below, which one is out of focus?
