A simple microscope uses a system of lenses to create a magnified image of a small object. Typically, it consists of two lenses: an objective lens (close to the object) and an eyepiece lens (close to the eye). The objective lens creates a magnified real image, which then becomes the object for the eyepiece. The eyepiece further magnifies this image, creating a virtual, enlarged image that we can see. The total magnification of the microscope is the product of the magnification of the objective lens and the magnification of the eyepiece. Understanding the principles of refraction and lens properties is key to building and using a microscope effectively.
Match the terms with their definitions:
| Term | Definition |
|---|---|
| 1. Objective Lens | a. The bending of light as it passes from one medium to another. |
| 2. Eyepiece Lens | b. The lens closest to the specimen, providing initial magnification. |
| 3. Magnification | c. The lens closest to the eye, further magnifying the image. |
| 4. Refraction | d. The process of enlarging the apparent size of an object. |
| 5. Resolution | e. The ability to distinguish between two closely spaced objects. |
