INTRODUCTION Optics is part of everyday life. The ubiquity of visual systems in biology indicates the central role, optics plays as the science of one of the five senses. Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it usually describes the behaviour 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. APPLICATIONS of OPTICS:- I would like to describe the numerous applications of optics in everyday life. Like, many people benefit from eyeglasses or contact lenses, and optics are integral to the functioning of many consumer goods including cameras. Rainbows and mirages are examples of optical phenomenon. Optical Communication provides the backbone for both the internet and modern telephony. The human eye, visual effects, etc are the main applications of optics. The human eye functions by focusing light onto a layer of photoreceptor cells called the retina. There are two types of photoreceptor cells, rods, and cones which are sensitive to different aspects of light. The optical power of the corrective lens is measured in diopters, a value equal to the reciprocal of the focal length measured in meters. The visual effects which we see in films, video, computer graphics, etc. are also called visual illusions. It differs from objective reality which is characterised by visually perceived images. The information gathered by the eye is processed in the brain to give a percept that differs from the objects being imaged.


Now, in everyday life, we use optical instruments being unaware of them. Like, photographic lenses, corrective lenses, and magnifying glasses while single mirrors are used in parabolic reflectors and rear view mirrors.

In the laboratory, we use optical instruments like microscopes, telescopes.

We use our cameras in mobile phones, shooting cameras which we are unaware of. The optics of photography involves both lenses and the medium in which the electromagnetic radiation is, it can be a plate, film, or charge-coupled device.

So, Whenever we see the colorful sky is due to the scattering of light off particulates and pollution. The last application in our everyday life from my side is atmospheric optics. The blue color of the sky is a direct result of Rayleigh scattering which redirects higher frequency sunlight back into the field of view of the observer.

CONCLUSION:-

We all are using optics in our everyday life by being aware of it or being unaware of it.

Optics is not just a branch of physics but also part of our daily life. Above I have mentioned some of them.

And we all our benefitting the optics use in modern civilisation and for high-speed internet, and many more.

And at last, I would ask you a question Have you ever wondered in our mobile phone camera that indirectly we are using the optics branch which we learnt in our 10th standard?
