Optics is a division of physics that concerns the behavior and properties of light. This includes light's interactions with matter, along with the development of instruments that use and/or detect it. The basis of a study in optics is the classical electromagnetic description of light. Since this is difficult to apply in practice, practical optics often uses simplified models, such as geometric optics. This treats light as a collection of rays that travel in straight lines. These rays bend when they either pass through or reflect off surfaces. Digging deeper, physical optics, which uses a more comprehensive model of light, includes wave effects like diffraction and interference. Finally, there are light effects that require quantum mechanics to explain them. Optics is relevant to many fields - photography, medicine (especially ophthalmology and optometry), certain engineering disciplines, and astronomy, to name a few. If you're studying this advanced field, you might wish to consider the benefits of optics tutoring. Varsity Tutors is here so you can find an excellent optics tutor today.
Optics students may study and/or research a wide range of topics, and Varsity Tutors can connect you with a tutor who is familiar with your particular area of study. That may be the nature of the absorption and admission of light, optical quantum information processing, remote sensing, diffractive optics, or others.
