Physics

4. A common eye condition in which near objects appear blurry. Also known as farsightedness.
6. A type of lens that is thicker in the center than at the edges and causes light rays to converge or focus.
8. A common eye condition in which distant objects appear blurry. Also known as nearsightedness.
9. An optical device that projects an enlarged image onto a screen or wall using a light source and lenses.
10. The ability to perceive and interpret visual information from the environment.
11. An optical device made of transparent material that refracts (bends) light and can be used to focus, diverge or converge light rays.

1. An optical instrument used to view distant objects. It typically consists of a combination of lenses or mirrors that magnify and focus the image.
2. The branch of physics that studies light and its behavior, including the properties and applications of lenses, mirrors, and other optical devices.
3. term used to describe a lens or other optical device that causes light rays to come together or converge at a focal point.
5. A term used in optics to describe an image that is not actually located at the position where it appears to be.
7. A solid material that is often used in the production of lenses due to its optical properties.
8. An optical device used to magnify small objects, often used in scientific research and medical diagnosis.
