An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically electromagnetic waves can be as long as the expansive width of the universe in one wave, to a wavelength the size of a quanta the smallest amount of energy that can be transmitted. That, however, is at this point in time negligible because we either cannot detect wavelengths so extremely large or infinitesimally small.

Electromagnetic Radiation, Visible Light and Human Health On a daily Essays on electromagnetic radiation, electrical energy finds ways into our homes, offices and place of work, this can be through house appliances, office equipments, etc.
Radiations emitting devices consist electronic devices: Most low-level electromagnetic radiation is those that are emanating from electrical power cables or high-power voltage lines. For many people are unaware of the health hazards that surrounding them as a result of electromagnetic radiation emanating from electrical devices, people are also unaware of the long-term effects of exposure to radiation.
People suffer from contamination and electro-smog caused by electromagnetic radiation; E-smog is a lot of electromagnetic fields which occupies the planet.
Esmog is caused by electrical and magnetic tools; they produce Esmog that causes invisibility that attacks human body affecting its biofield. There are two classifications of electromagnetic radiation: Examples of ionizing particles x rays or gamma rays are the result of ultraviolet and high frequencies of electromagnetic radiation.
Exposure to x-ray and gamma rays poses a potential risk to human health. There is another electrical field known as a static field which is caused by ions produced from the synthetic materials make humans feel unwell, will the residual of magnetism commonly occurs from metal in the bed, change its magnetic fields to body discomfort.
A lot of effort currently as been put towards the research of electromagnetic radiation about cancer, the study is looking at possible carcinogenic effects of electromagnetic fields.
Visible light and its impact on human health There have been several UV light radiation research on its effect to human health since the UV light is one of the radiation in the spectrum. There is also a concern on the effects of visible light and inferred light to people's health.
The goal of the research is to highlight the effects of visible light on the skin. As a result of advances in the comprehension of skin optics, and thorough studies in regards to the assimilation range of endogenous and exogenous skin chromophores, different biologic impacts have been appeared to be applied by visible light radiation including erythema, pigmentation, warm harm and free radical creation.
It has additionally been demonstrated that visible light can affect indirect DNA damage through the era of sensitive oxygen species. Besides, many photodermatoses have an activity range in the unmistakable light range, despite the fact that the majority of the as of now available sunscreens offer, assuming any, feeble assurance against the visible light.
On the other hand, given its cutaneous biologic impacts, noticeable light is utilized for the treatment of an assortment of skin maladies and stylish conditions as lasers, extreme beat light, and photodynamic treatment.
Why is artificial light a concern to human health? Artificial light consist of visible light and UV light and Infrared radiations, there is a concern that a certain level of emission from this light may be harmful to human health.
The fact that natural light from the sun can disrupt the normal function of the body, for instance, can cause hormonal imbalance.
The potential of the UV and blue light to cause harm is great, such as skin-light sensitivity. For example, light from an artificial source such as fluorescent lamp emits diodes LEDs which cause a lot of skin diseases.
The time of exposure to visible light should also be controlled to avoid its harmful impact on human health. Exploring the public health impact of electromagnetic radiation Overview of electromagnetic spectrum The term radiation refers to the energy given off or away from the source.
The type of this energy is different with physical properties, which can be measured using its frequency and wavelengths. The electromagnetic spectrum refers to a group of energy that comes from various sources. What this type of energy is emanating is given off is the kind of Electromagnetic radiation.
The ones with high frequencies are the gamma, x rays and ultraviolet lights. While those lower in the electromagnetic spectrum are radio waves and microwaves. Most types of energy with high frequencies are invisible and imperceptible to a human.
The naked human eye cannot see, unless with the use of specialized tool most of this electromagnetic waves cannot be detected, for this reason, people cannot appreciate their exposure to the field. Prolonged exposure to high-frequency electromagnetic radiation has the potential to harm human body cells in a process known as ionization.
They cause cell damage through altering the atomic structure and composition of the cell. Ionizing radiation breaks the chemical bond and introduces free radical building. Prolonged exposure to electromagnetic radiation such as gamma may harm DNA and cause cell mutation, leading to malignancy or destruction of the cell.
Electromagnetic radiation and reproductive dysfunction There have been many adverse pregnancy complications that have been linked to maternal electromagnetic radiation exposure; such outcomes include miscarriages, preterm delivery, congenital anomalies, and stillbirth. Research as pointed out that long-term exposure of electromagnetic field may hurt a pregnant woman.
It is further been established that industries with higher exposure to high-frequency radiation have offspring with large number of brain and spinal tumour.
Electromagnetic radiation with cancer Many types of research have accused that electromagnetic emissions are carcinogenic in nature. For instance according to international journal for cancer, published a case study on population, showing the relationship between childhood leukaemia and the electromagnetic fields in Japan.The electromagnetic spectrum, in order of increasing frequency and decreasing wavelength, consists of radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
The eyes of various organisms sense a somewhat variable but relatively small range of frequencies of EMR called the visible . Electromagnetic Radiation Essay Examples. 21 total results. Cell Phones and Capabilities of Being Reached. words. 1 page.

Ionizing radiation has high energy and shorter wavelengths than does the other side of the electromagnetic spectrum, which includes the lower energy, longer wavelengths, known as nonionizing radiation.
Electromagnetic Radiation's Effect on the Lifespan of Gryllidae Abstract The main objective in this experiment was to determine if electromagnetic radiation would affect the lifespan of a population of Gryllidae.
The 21 Gryllidae were placed in three groups of seven each. Each group was cov.
