The Nature of Light

Introduction Invisibility is one of invisibility in Predator movies and Harry Potter's most sought after abilities and fantasies and plays an important role in science fiction. When you read the article "Scientists create invisible cloaks", you can see that scientists are still seeking this ability today. In order to achieve this goal, researchers are studying while deepening their understanding of the nature of light. The current study is the details of the research conducted by Thomas Young and Francesco Grimaldi. These studies form the basis of understanding of the nature of the present light.

The essence of light is Thomas Young's theory. Thomas Young was the person who initially presented the evidence of the nature of the light waves and he did not think about the theory of light and waves first, but Christian Huygens pointed out this point. Experiment: Yang's double seams. Thomas Young suggests that the interaction of two beams can cause constructive or destructive interference. In areas where constructive and destructive interference occurs, the emitted electromagnetic waves can change the phase and change constantly.

Light waves are electromagnetic waves that pass through vacuum in outer space. Lightwaves are generated by vibrational charges. The nature of this electromagnetic wave is beyond the scope of the physics classroom tutorial. For our purposes it is sufficient simply to say that electromagnetic waves are transverse waves with electrical and magnetic components. The lateral nature of electromagnetic waves is quite different from the other types of waves described in the Physical Classroom Tutorial. Let's assume we use normal airtightness to simulate electromagnetic wave behavior. When electromagnetic waves come to you, you will observe the tension oscillations that occur on one or more oscillating surfaces. If you want to observe narrow waves coming in a narrow direction, this is quite different from what you might notice.

Light has both particle and wavy characteristics. The light represents a portion of the radiant energy having a wavelength visible to the naked eye, about 390 to 760 nm. This is a very narrow area of ​​the electromagnetic spectrum. Particle characteristics of light are usually expressed as quantum or photon, light with individual energy packets, each with a specific associated wavelength. In other words, light can be defined as electromagnetic energy propagating in discrete particles called quantum or photon. The energy of a chemical reaction is usually expressed in kilocalories per mole of chemical substance (1 mole = 02 x 1023 molecules). Therefore, light energy is usually expressed in terms of quantum number of moles or each Einstein's kcal (1 mol quantum or 1 Einstein = 02 x 1023 quantum).
