Optical instruments are devices that use the principles of optics to aid in the observation or measurement of objects. They are widely used in various fields, including physics, astronomy, medicine, and engineering. In Class 12 Physics, you will typically study the following optical instruments:

Microscope: A microscope is an optical instrument that is used to magnify small objects or samples that cannot be seen by the naked eye. It consists of an objective lens and an eyepiece, which work together to produce a magnified image of the specimen.

Telescope: A telescope is an optical instrument used to observe distant objects, such as celestial bodies. It gathers and focuses light to create a magnified image. There are two main types of telescopes: refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors.
