Electromagnetic Radiation

From the same event on the same source both should arrive at the same time, unless delayed by an intervening medium.

IR, Red, Orange in a typical fire. A pure hydrogen fire however gives off only IR and a barely visible amount of Blue. Metallic salts in the flame will add their own characteristic colors (e.g. sodium: Yellow, copper: Green).

Yes, it can do that. Electrosmog from the inverter system connected to the solar

panels cause that symptoms and if you continue to be close to the fields you will

develop EHS (Electromagnetic Hyper Sensitivity). It can be a very big handicap in

the modern community to get such an illness.

===========================================

Another answer / opinion / perspective:

-- The target of the related link makes no mention of anything called "electro-smog".

-- The target of the related link is talking about electromagnetic fields. There are

no electromagnetic fields associated with a solar electricity system. The blue cells

in the collecting panel are completely passive generators of DC, and the storage

part of such a system is a bunch of car batteries.

-- Even if the system were a potent source of intense electromagnetic radiation,

the hardware is all on the roof and in the basement ... not in the rooms where you

spend most of your time.

-- The target of the related link bases its call for action on the statement that the

long-term results of exposure to electromagnetic fields are unknown. Its organizers

are apparently unaware that the sun is a potent source of electromagnetic fields,

and that exposure to additional man-made sources has been a fact of daily life for

roughly the past 100 years, with the number of sources increasing daily.

-- If you must have something electromagnetic to worry about, here are two things

that worry me:

. . . . . The cell-phone transmitting antenna that you hold about an inch and a half

from your brain.

. . . . . The high-voltage, forced-air cooled cavity magnetron operating at 2.5 Gigahertz,

that generates a couple of kilowatts of RF energy which then blasts through a rectangular

waveguide and fills a resonant chamber with standing waves of intense electrostatic and

magnetic fields ... all of this right in front of you while you're standing there watching it,

waiting for the left-over meat-loaf in the "microwave" to finish heating up.

Possible negative effects of infrared non-ionizing radiation include skin burns, eye damage, and potential heat-related injuries. Prolonged exposure to intense infrared radiation can also cause tissue damage and dehydration. It's important to limit exposure and use protective measures when working with infrared sources.

Yes, supernovas emit gamma rays as part of the explosion process. These gamma rays carry a significant amount of energy and are one of the most powerful forms of radiation emitted during a supernova event.

Exposure to ionizing radiation can potentially cause damage to cells, DNA mutations, an increased risk of cancer, and various health effects depending on the dosage and duration of exposure. It is important to limit exposure to ionizing radiation and follow safety guidelines to minimize risks.

The human eye can detect a small portion of the electromagnetic spectrum, known as visible light. This range spans from approximately 400 to 700 nanometers in wavelength, corresponding to colors we perceive as violet to red.

Gamma rays are the most penetration rays because of its shortest wave length...

The formula for the speed of electromagnetic radiation in a vacuum is given by c = λν, where c is the speed of light, λ is the wavelength, and ν is the frequency. Additionally, the energy of a photon of electromagnetic radiation is given by E = hν, where h is Planck's constant.

der, cause u got poo on it

The wavelength of a light wave is given by the formula: wavelength = speed of light / frequency. In a vacuum, the speed of light is approximately 3 x 10^8 m/s, which is 300,000,000 m/s. Therefore, the wavelength of a light with a frequency of 40 x 10^14 Hz is 7.5 x 10^-7 m, or 750 nm.

I presume you mean for medical imaging. X-rays are ideal because they penetrate (1) skin and muscle fairly easily but (2) bone with difficulty. As such, radiologists can examine bone structure inside a body.

Alpha particles and beta particle can not do (1).

Gamma rays do (1) extremely well, but also blast through bone as well. They blast through organic tissue so well that they are quite dangerous to any life on Earth.

The infrared radiation emitted from a candle is a type of electromagnetic radiation that is not visible to the human eye. It is produced as a result of the heat generated by the candle flame and can be felt as warmth by our skin.

Metals such as aluminum, silver, and gold are known to be good reflectors of electromagnetic radiation, including visible light and infrared radiation. Their smooth and shiny surfaces allow for efficient reflection of a wide range of electromagnetic wavelengths.

Photons of UV B radiation are more energetic than photons of UV A radiation. UV B radiation has a shorter wavelength and higher energy compared to UV A radiation, making it more damaging to the skin and eyes.

When you try to stump me with a multiple-choice question, please

be good enough to include the list of permissible choices.

Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.

Perhaps you are after the word band or bandwidth.

Extreme ultraviolet and X-rays are mostly absorbed by the Earth's atmosphere before reaching the surface. This absorption helps protect living organisms from the harmful effects of these high-energy radiations.

There are only two types of radiation.

1. Electromagnetic

Under this we have gamma radiation, X radiation, light and heat

2. Particle radiation

Under this we have alpha and beta.

That depends a lot on the order of magnitude of the electromagnetic radiation in question. If it's radio waves or microwaves, you can use a coil of wire hooked up to an oscilloscope (preferably a digital one), and use a function on the device to measure the wavelength.

If it's something between infrared and ultraviolet, including visible light, you'd have to use a special light sensor, though I'm not sure of the name. However, there is a relatively simple experiment that can give you a rough estimate of the wavelength of light you can see:

As for things like X-rays and Gamma rays, sorry, but I have no clue, though I can speculate that it would be possible to take a diffraction based approach such as the one outlined on the link above, but the equipment would surely be more complicated. Not to mention that such forms of radiation are very dangerous.

For the frequency, first convert the wavelength to meters (divide the number of Angstroms by 1010), then use the formula: wavelength x frequency = speed. Using the speed of light in this case. Solving for frequency: frequency = speed / wavelength.

To get the photon's energy, multiply the frequency times Planck's constant, which is 6.63 x 10-34 (joules times seconds).

The short answer is "No".

The long answer is as follows: "Light is a form of radiation, and defined as a number of photons. Each photon, when emitted, has a certain amount of energy. This is dictated by the amount of energy the particle has when it emits light. Higher levels of light require more energy to produce. Lower levels of energy produce light like microwaves or infra-red. Medium levels include visible light, ultraviolet and such. High levels, which require enormous amounts of energy, include things like X-rays and Gamma rays. Remember that there's no real difference between forms of light. Each category simply includes light with energy between one level and another (E.g Ultraviolet light exists between 10nm and 400nm). The number is arbitrary, however to a human there is still an important difference. So no, they aren't the same.

Gamma rays have frequencies higher than x-rays in the electromagnetic spectrum. They have the shortest wavelengths and highest energies in the spectrum.
