When a light beam strikes a surface, it can have one of three effects: reflection, refraction, or absorption. When a ray of light strikes a regular surface, the majority of it is absorbed. As a result, we can define mirrors as polished surfaces that are coated with Mercury (chemical symbol Hg) to reflect the majority of the light that strikes them. Based on the reflecting surface, we can categorize mirrors as convex, concave, or planar mirrors. So, let's get to know the concepts behind these three sorts of mirrors, as well as their properties, functions, and applications.
Plane Mirror—provide virtual images that are upright, reversed left-right, the same distance from the mirror as the thing, and the same size as the object.
Periscopes and kaleidoscopes, vehicles, shaving mirrors, dentists' mirrors, torch lights, solar cookers, and security-related applications are all examples of plane mirrors.
A mirror with a curved reflecting surface is known as a curved mirror. Convex or concave surfaces are possible. The surfaces of most curved mirrors are formed like a section of a sphere, however different shapes are occasionally utilized in optical equipment.
Concave Mirror—Light is reflected inward by concave mirrors, resulting in a single focal point. As a result, they're usually utilized to concentrate light. Depending on the distance between the mirror and the object, a concave mirror will produce different image types. Concave mirrors are known as converging mirrors because they catch light as it falls on them and redirect the parallel incoming rays. Concave mirrors are used in automotive headlights, reflecting telescopes, torch lights, and other applications.
Convex Mirror—has a curved reflective surface that bulges out towards the light source. This protruding surface reflects light outwards rather than focusing it.
Because the focal point and the center of curvature are imaginary spots in the mirror that cannot be reached, these mirrors create a virtual image. As a result, images are formed that cannot be displayed on a screen since they are formed inside the mirror. From a distance, the image appears smaller than the thing, but as the object approaches the mirror, the picture grows larger.
Convex mirrors are utilized as rear-view mirrors in automobiles, optical instruments, calling bells, and other applications.
But did you realize that improperly placed automobiles mirrors are a common cause of accidents?
When driving an automobile, human error is frequently the cause of accidents. We usually talk about driving at a moderate pace, staying in the lane, and not driving when inebriated, yet despite all of this, many people fail to correctly adjust their side mirrors, resulting in accidents.
And did you know that the Philippines has a specific law that protects people's health? How may this law be of assistance to us?
Philippines' Consumer Protection Act
(RA 7394)
— It is a national strategy aimed at safeguarding the interests of consumers, buyers of goods and services, and to improve consumer welfare in general, and uphold ethical norms for both the commercial and industrial sectors that are affected.
In Republic ACT NO. 8293
This Act shall be known as the "Philippine Intellectual Property Code."
— Declared that a functional intellectual and industrial property system is critical to the development of domestic and creative activity, as well as facilitating technology transfer, attracting foreign investment, and ensuring market access for our products. For the periods specified in this Act, it shall defend and secure the exclusive rights of scientists, inventors, artists, and other gifted individuals to their intellectual property and achievements, particularly when beneficial to the people.
Overall, mirrors have had a crucial impact on humanity and everyday life – except from increasing our vanity, of course – from medical equipment to vehicles.
