A compound microscope makes a small object lookbigger so that our eye can see it. Acompound microscope consists of two converging lenses of short focal lengths:the objective lens and the eyepiece lens.
A telescope is used to make distant objects look closer and appear bigger. It consists of two converging lenses: the objective lens with a long focal length and the eyepiece lens with a short focal length.The optical system of a telescope is similar tothat of a compound microscope. In both instruments, the image formed by an objective lens is viewed through an eyepiece. The key difference is that thetelescope is used to view large objects at large distances, and the microscope is used to view small objects at a very close distance.
QUESTION
1. What do you call the lenses that are thicker at themiddle than at the edges?
C. double concave
B. concave lenses
D. convexo-concave
A. Convex lenses `
