An FM radio station broadcasts electromagnetic waves at a frequency of 125MHz (M=mega=10u2076). These radio waves have a wavelength of 2.40m. What is the speed of the radio wave?

Radio broadcasting electromagnetic waves

An FM radio station broadcasts electromagnetic waves at a frequency of 125MHz (m=mega=106).

These radio waves have a wavelength of 2.

40m.

What is the speed of the radio wave?Well, the formula you need is,speed = wavelength times frequency,You do the math.

Radiotherapy electromagnetic waves

high frequency like x-ray is commonly used.

the idea is to focus the high frequency beam on to cancer cells and kill them.

it is alternative for cutting effected area.

Which of the electromagnetic waves is used in cancer therapy

It is possible - but it would have nothing to do with the satellite dish.

,First, I believe the satellite dish only receives - unless they have them actually transmitting to the satellite - for an internet connection or something like that - but last time I checked, they only received.

,Second, thereu2019s no evidence that non-ionizing radiation can cause brain tumors - see Gary Larsons answer to Can WiFi cause cancer? WiFi, cell phones and most satellite communication uses radio waves in the microwave portion of the electromagnetic spectrum - which cannot produce ionizations in atoms - a necessary event in cancer induction by radiation.

There are links to other pertinent answers contained in the referenced answer above.

,We all have the same chance of developing a brain tumor (unless you actually received ionizing radiation to your brain in the past - like radiation therapy - or were exposed to nuclear fall-out - only a small part of the population has to worry about that).

Sterilization of medical instruments electromagnetic waves

Im going to assume, based on how the question is worded, you mean elective modifications with no medical benefits.

i.

e piercings or tattoo.

,In my opinion, something that has a bit of a social taboo to it that I dont think should is magnet implants.

,The procedure is actually quite simple.

However Im going to refrain from explaining it all, simply because I dont want anybody trying it from one quora post alone.

It consists of, basically, implanting a specially designed biomagnet into the pad of one of your fingers.

Since the pads of your fingers are so nerve dense, and since neodymium magnets vibrate when exposed to electromagnet waves, the procedure gives its recipient the ability to sense electromagnet fields innately.

Almost like another sense.

,A biomagnet for implant,This sounds great.

The problem is though, these u201cnew innovationsu201d in body modification exist in a legal grey area between what a piercer can perform and u201cpracticing medicineu201d which would be illegal for a piercer to do.

,Remember when I said that the fingers are very nerve dense? That means that it is exceptionally painful to cut directly into.

Ive even heard of people blacking out mid-procedure due to the pain.

This could be easily managed, with the use of digital anesthesia.

However that is outside of the current u201cscope of practiceu201d of peircers leading people to attempt this with poor preparation, in poor conditions, with subpar equipment.

There isnt even any sources to acquire these biomagnets that have stringent quality controls.

,The pioneers of this form of body modification, called biohackers or u201cgrindersu201d, really have done stellar work in making this safer for those so inclined to do at home, but since your still quite literally doing bathroom surgery there are still very real risks.

Risks that could easily be mitigated if this could be done by competent and educated technicians in sterile, or at least aseptic, conditions with quality single-use sterile instruments.

I know well probably never see it, but I would love to see an FDA approved biomagnet platform.

,Nothing here is medical advice.

How does electromagnetic radiation affect living things and the environment

in 2015, 215 scientists from 41 countries communicated their alarm (about the potential of 5G) to the United Nations (UN) and World Health Organization (WHO).

[xvi] They stated that u201cnumerous recent scientific publications have shown that EMF [electromagnetic fields] affects living organisms at levels well below most international and national guidelinesu201d.

As already stated, more than 10,000 peer-reviewed scientific studies demonstrate harm to human health from RF/MW radiation.

[xvii] [xviii] Effects include:,Alteration of heart rhythm[xix]Altered gene expression[xx]Altered metabolism[xxi]Altered stem cell development[xxii]Cancers[xxiii]Cardiovascular disease[xxiv]Cognitive impairment[xxv]DNA damage[xxvi]Impacts on general well-being[xxvii]Increased free radicals[xxviii]Learning and memory deficits[xxix]Impaired sperm function and quality[xxx]Miscarriage[xxxi]Neurological damage[xxxii]Obesity and diabetes[xxxiii]Oxidative stress[xxxiv]Autism[xxxv]ADHD[xxxvi] [xxxvii]Asthma[xxxviii]Negative altered mental states, including increased depression, anxiety, and suicidal tendencies[xxxix]It is already clear from over 10,000 studies on 2G, 3G, and 4G that these wireless network radio frequency (RF) radiation network systems are causing significant acute and chronic health problems, including life-threatening diseases such as cancer, heart disease, type-2 diabetes, and mental disturbances, such as depression, anxiety, and increased suicidal tendencies.

,Beyond the statements of informed individuals decrying the 5G u201crolloveru201d, there are also major organizations warning of its dangers.

The International Appeal to Stop 5G on Earth and in Space currently boasts approximately 31,300 signatories as of January 11th, 2019.

They write,,u201cWe the undersigned scientists, doctors, environmental organizations and citizens from (__) countries, urgently call for a halt to the deployment of the 5G (fifth generation) wireless network, including 5G from space satellites.

5G will massively increase exposure to radio frequency (RF) radiation on top of the 2G, 3G and 4G networks for telecommunications already in place.

RF radiation has been proven harmful for humans and the environment.

The deployment of 5G constitutes an experiment on humanity and the environment that is defined as a crime under international law.

u201dEven before 5G was proposed, dozens of petitions and appeals[i] by international scientists, including the Freiburger Appeal signed by over 3,000 physicians, called for a halt to the expansion of wireless technology and a moratorium on new base stations.

[ii] In 2015, 215 scientists from 41 countries communicated their alarm to the United Nations (UN) and World Health Organization (WHO).

[iii] They stated that u201cnumerous recent scientific publications have shown that EMF [electromagnetic fields] affects living organisms at levels well below most international and national guidelinesu201d.

These concerns have a strong scientific foundation.

More than 10,000 peer-reviewed scientific studies demonstrate harm to human health from RF radiation.

[iv] [v]In summary, weu2019ve been given a story of how good it is that we can have u201csmartu201d homes, u201csmartu201d businesses, u201csmartu201d highways, u201csmartu201d cities and self-driving cars.

Virtually everything we own and buy, from refrigerators and washing machines to milk cartons, hairbrushes, and infantsu2019 diapers, will contain antennas and microchips and will be connected wirelessly to the Internet.

Weu2019re being told that this is a good thing, but itu2019s not if we value our physical, mental, moral, and spiritual health.

In other words, no matter how u201cultra-convenientu201d these ultra u201csmartu201d devices, agreeing to be seduced by the promises of convenience is potentially not too smart.

Which electromagnetic wave carries more energy than the others

Gamma rays , having highest frequency.
