Are EM waves harmful to humans?

HomeArticles, FAQAre EM waves harmful to humans?

There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

Q. How do EM waves travel?

These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Q. How fast do EM waves travel?

Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.

Q. What are the benefits of EM waves?

The killing and destructive power of electromagnetic radiation can be used constructively for curing the incurable diseases by eradicating the disease producing pathogens and micro organisms like bacteria, virus & fungi.

Q. What are the disadvantages of EM waves?

Hazards of electromagnetic radiation

  • microwaves cause internal heating of body tissues.
  • infrared radiation is felt as heat and causes skin to burn.
  • X-rays damage cells causing mutations (which may lead to cancer) and cell death – this is why doctors and dentists stand behind protective screens when taking lots of X-rays.

Q. Can we live without em waves?

Radio, Microwave, Infrared, Visible light, Ultraviolet, X-rays, Gamma rays. No EM wave means no sight. No transfer of energy from the sun to the Earth, so no life.

Q. Can EM waves travel through water?

Electromagnetic propagation through water is very different from propagation through air because of water’s high permittivity and electrical conductivity. Plane wave attenuation is high compared to air, and increases rapidly with frequency.

Q. Can you hear sound waves?

We hear when sound waves travel through the air to our eardrum, across our middle ear, into our inner ear, and finally to the auditory centers of our brain. Our ears are always on and are continuously carrying sounds along this hearing pathway.

Q. Why do I hear radio in my head?

Musical hallucinations usually occur in older people. Several conditions are possible causes or predisposing factors, including hearing impairment, brain damage, epilepsy, intoxications and psychiatric disorders such as depression, schizophrenia and obsessive-compulsive disorder.

Q. What wavelength can humans see?

380 to 700 nanometers
