9/26/2023 0 Comments Visible light spectrum![]() The glow sticks typically consist of two chemical compounds, namely hydrogen peroxide and fluorescent dyes. The light that is radiated by the glow sticks into the environment can be seen easily by naked eyes and therefore, is yet another example of visible light in real life. The light energy produced by the fire can be seen easily by naked eyes therefore, fire is one of the best examples of visible light in real life. Fire tends to release heat, smoke, and light as by-products. It is a chemical process that is highly exothermic in nature and causes rapid oxidation of the fuel. The light produced by an electric light bulb is yet another example of visible light in real life.įire is produced as a result of the combustion of combustible elements. When the switch is connected and a closed circuit is formed, the electric current passing through the filament of the electric bulb tends to increase the temperature to a level after which it begins to produce light. It consists of a filament made up of tungsten. This set of colours is abbreviated as VIBGYOR and can be observed easily by passing the sunlight through a glass prism.Īn electric light bulb is a common light source used in households. The sunlight appears to be white in colour, but contains a set of seven colours arranged in a specific order according to the value of wavelengths. The light that we receive from the sun is a prominent example of visible light in real life. Visible light is used to create a sense of sight in the eyes of a person that helps him/her to visualize the structure, colour, and appearance of objects present in the surroundings. Here, the red colour has the longest wavelength, whereas violet has the shortest wavelength. This arrangement of colours is usually abbreviated as VIBGYOR. It is a combination of seven colours of different wavelengths arranged in a specific order, i.e., violet, indigo, blue, green, yellow, orange and red. ![]() The visible light is also known as white light. The visible segment of light is formed by a section of the electromagnetic spectrum that has a wavelength range lying between 0.4 to 0.7 µm. ![]() Visible light is the spectrum of light that humans can see easily with naked eyes.
