Light energy is a kind of kinetic energy that allows people’s eyes to see different light shades. The type of electromagnetic radiation produced by hot objects, such as lasers, lamps, and the sun, are characterized by light travelling in the form of a wave. Light energy is swift and moves faster, with a speed of 186,282 miles per second.
Light includes photons that are minute energy bundles. As the atoms of an object heat up, photons are emitted and produced. The electrons are excited by heat and accumulate extra energy, emitted as a photon, and the material becomes hotter with more photons.
Light has different types of essential properties, and these are as follows:
Reflection of light occurs as the waves encounter a reflecting surface or its borders, not absorbing the radiation energy while the waves bounce back from the body. When light rays reflect a body, they travel from one transparent medium to another or move through a medium with a frequently altered composition. According to the law of reflection:
The definition of refraction states that it is a process where the speed of light changes as it passes from a medium to another medium, resulting in light beams’ bending. Refraction of light obeys two of the following laws:
One of the simplest examples of refraction is a half-filled glass of water with a pencil. See how the crayon looks normal above the water, but it seems much more significant and curved under the water. It happens as a result of refraction.
A mirror is a reflective plate that springs from light and produces an image or a virtual image. When an object is set before a mirror, it is visible as its reflection in the mirror. The item is the ray source, and the representation consists of the reflected rays. The images are known as real images or composite images based on the relationship between light. A real image is produced when the light rays converge, while virtual pictures arise due to the light rays’ apparent divergence.
Mirrors are of two types, namely a plane mirror and a spherical mirror. A plain reflecting mirror has a flat and smooth reflection, while a spherical mirror or curved mirror is a mirror with a constant curve and a constant curvature radius.
Curved mirrors are mirrors with curved surfaces on one edge. There are two types of curved mirrors, namely convex and concave mirrors. Spherical mirrors with interior surfaces are known as convex mirrors, while spherical mirrors with exterior surfaces are known as concave mirrors.
There are numerous uses of curved mirrors and are listed as follows:
A variety of technological advances have turned around light over the last century. Optical research has allowed us to develop our knowledge of light energy and its relationships with all sorts of matter.
