What is the importance of physics in optics?

Answer 1

Most Telecommunication uses electric pulses through wires. A little bit occurs through fiber optic cables. Physics describes the behaviors of both electricity and light. All of telecommunication is physics. Really everything is.

Answer 2

Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.[1] Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.[1]

Most optical phenomena can be accounted for using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be accounted for in geometric optics. Historically, the ray-based model of light was developed first, followed by the wave model of light. Progress in electromagnetic theory in the 19th century led to the discovery that light waves were in fact electromagnetic radiation.

Some phenomena depend on the fact that light has both wave-like and particle-like properties. Explanation of these effects requires quantum mechanics. When considering light's particle-like properties, the light is modeled as a collection of particles called "photons". Quantum optics deals with the application of quantum mechanics to optical systems.

Optical science is relevant to and studied in many related disciplines including astronomy, various engineering fields, Photography, and medicine (particularly ophthalmology and optometry). Practical applications of optics are found in a variety of technologies and everyday objects, including mirrors, lenses, telescopes, microscopes, lasers, and fiber optics.

Answer 3

Electronics Engineering is one of the most significant and most refined parts of the building. It has made us accessible the types of gear like Television, Radio, PCs, phones, and so on. Electronics has a significant job in improving profitability in enterprises like oil, vitality, agribusiness thus numerous other significant segments of the economy.

A electronics engineer works in gatherings to configuration, create, produce, test and direct the assembling of multiple items and frameworks, for example, electronic hardware and parts.

He works for various ventures including emergency clinics, PC enterprises, electronic information handling frameworks for correspondence and in guard, and so forth. They work with microchips, fibre optics, media transmission, TV, radios, and so on. Gadgets building is a quickly developing division where there is a brilliant opening for work for the gifted experts.
