Visible Light: Exploring the Spectrum of Electromagnetic Radiation
Light is a form of energy that is composed of electromagnetic radiation (चुंबकीय विकिरण). It occurs naturally from sources such as the sun and stars. The part of this radiation that humans can see with their eyes is known as visible light. In this article, we will explore the types of visible light, its properties, and its applications in daily life.
Types of Light in the Visible Spectrum
Visible light is a type of electromagnetic radiation (चुंबकीय विकिरण) that falls between ultra-violet rays and infrared radiation (वातावरण विकिरण) in the electromagnetic spectrum. It is usually divided into 7 different colours, including red, orange, yellow, green, blue, indigo and violet.
Table 1: Colours of the Visible Light Spectrum
| Color | Wavelength (nm) |
|---|---|
| Red | 620–750 |
| Orange | 590–620 |
| Yellow | 570–590 |
| Green | 495–570 |
| Blue | 450–495 |
| Indigo | 420–450 |
| Violet | 380–420 |
Properties of Visible Light
Visible light is a form of energy that travels in waves and has both electrical and magnetic fields (विद्युत और चुंबकीय क्षेत्र). It is non-ionizing and has a wavelength range of between 400 and 800 nanometers (नांमेटर). The higher the frequency of visible light, the shorter its wavelength will be. As a form of energy, it has the ability to behave both as particle and wave, which is known as wave-particle duality (तरंग-अंश डुय्लटिटी).
Uses of Visible Light
Visible light has a number of uses in everyday life. It is used to provide illumination for indoor and outdoor spaces, and is necessary for human vision. It is also used in photography, cinema, and various industrial applications. Visible light can also be used to carry information. This is done with fibre optic cables, which are used for telephone lines, internet connections and television cables.
Conclusion
In conclusion, visible light is an important form of electromagnetic radiation. It has many different applications, from providing illumination and enabling human vision, to carrying information over fibre optic cables. The wavelengths of the visible spectrum range from 400 nanometers to 800 nanometers. Understanding the properties and applications of visible light can be useful in countless ways.
