About This Product
A simple telescope lets students see how an objective and an eyepiece combine to magnify distant objects, and why the image appears inverted. They can work out magnification from the focal lengths and trace the ray paths through the tube. Schools, colleges and institutes in United Kingdom, Iceland, Indonesia, Bhutan, Mozambique and Djibouti can order the Simple Telescope from Educational Instrument.
