Ray Optics and Optical Instruments Important Questions for NEET Overview 

Ray optics is the study of light in the form of rays. It explains how light travels, reflects, and refracts through different mediums. Optical instruments are devices that use light to form images, such as microscopes, telescopes, and cameras. These concepts are very useful in real life and in various fields of science and technology.

What is Ray Optics and Optical Instruments?

Ray optics deals with the behavior of light when it travels in straight lines and interacts with different surfaces. It explains the principles of reflection, refraction, and dispersion. 

Optical instruments are tools that use lenses and mirrors to enhance or magnify images. Some common optical instruments include the human eye, magnifying glass, periscope, and binoculars.
