Answer» Simple microscope: 1. In a simple microscope, only one convex lens is used. 2. In this case, the object is placed within the focal length of the convex lens. 3. In this case, the image is erect. 4. It is used to observe minute parts of a watch, to read words in small print, etc. Astronomical refracting telescope: 1. In an astronomical refracting telescope, two convex lenses, objective lens and eyepiece are used. 2. In this case, the object is far away from the objective lens. 3. In this case, the image is inverted. 4. It is used to observe satellites, planets, stars, etc.
