Light is a form of energy that lies in the visible region of the electromagnetic spectrum (Light Spectrum). Outside of the visible spectrum, there are other electromagnetic wavelengths such as ultraviolet and infrared. Light covers a wide electromagnetic spectrum with the combination of these different wavelengths.
Light travels at a specific speed, approximately 299,792 km/sec in a vacuum. Light can propagate in vacuum, in air, in water, in transparent materials such as glass, and in many other media. Photons are produced as a result of charges vibrating in an electromagnetic field, and these photons provide the transport of light.
Light is used in many different applications, not only satisfying the sense of sight, but also playing an important role in communications, medicine, optics, photography, astronomy and many other fields.
It is an electromagnetic wave carried by the movement of particles called photons . Electromagnetic waves are energy carriers formed by the interaction of electric and magnetic fields. Light is a combination of electromagnetic waves with different wavelengths. The colors we perceive visually correspond to these different wavelengths. Light includes red, orange, yellow, green, blue, indigo and violet among the wavelengths in the visible spectrum.
Another important property of light is that it contains a property known as wave-nuclear duality. This property refers to the ability of light to exhibit both wave and particle properties. The quantum theory of light explains how light exhibits this duality.
A report released by the United States Environmental Protection Agency (EPA) in 2016 reveals that indoor air, such as home and workplace, is 2 to 5 times more polluted than outdoors. The main causes of this pollution are insufficient ventilation, burning of candles containing toxic substances, and room odors and chemicals mixed with air from detergents used in house cleaning.The detergents you use for cleaning not only pollute the air of your home. The waste of these detergents passes through your sink and drain pipes and mixes with water and damages many species, especially marine creatures, as part of its life cycle. The effects of these substances on almost all of the standard detergents to the nature are as follows;
Sles
Substance, known as sodium laurel ethylene oxide, is widely used in soaps and shampoos, toothpaste and household cleaning products. It provides foaming of cosmetics and cleaning products. When mixed with water, it has been found to be a toxic substance for fish and other sea creatures.
Phosphate
Phosphate, which is also used as a nutrient in fertilizers, increases the rate of nitrogen and phosphate in water when it is mixed with sea water. This causes plants such as seaweed to grow and increase much faster than normal, thus reducing the oxygen rate in the water and creating an environment that other sea creatures cannot survive.
Clorine
Chlorine, which is used as a bleach in detergents and bleaches, is one of the serious environmental threats. This substance, which is also used as a chemical weapon in the First World War, has been banned or restricted in many countries in order to protect the environment and human health. When chlorine is used in the home, it combines with respiratory tract, moisture in the larynx, throat and lungs, causing an acidic effect. Chlorine, which mixes with water as waste, interacts with other elements and minerals in the water and hosts dangerous toxic substances.
These substances, which emerged as a result of this interaction and referred to by names such as dioxins, furan and PCDD, are known as "permanent organic pollutants" since they do not stick to the soil and water and disappear for many years. Greenpeace; It qualifies dioxin, which causes diseases such as cancer and endocrine disruptions, as one of the most dangerous chemicals faced by science. Since even the effects of a small amount of chlorine mixed with air or water continue for many years, it easily reaches the soil and sea creatures and poses a threat to human life by being easily included in the food chain.
