Why an electromagnetic wave is able to produce both an electric field and a magnetic field because?
The question founders on the rocks of a chicken/egg conundrum.
The presence of both an electric field and a magnetic field is required
in order to produce an electromagnetic wave.
Why are some parts of the electromagnetic spectrum are not used for communication?
-- Because they can't be efficiently transmitted or collected, on account of the
ridiculously humongous antenna size required.
-- Because they're too strongly absorbed by atmospheric gases or water vapor.
-- Because they can't be generated with currently available technology.
What frequency range of light is visible?
The visible light spectrum ranges from approximately 400 to 700 nanometers in wavelength, corresponding to a frequency range of about 430 to 750 terahertz. This spectrum includes the colors of light that human eyes can perceive, from violet to red.
What property determines a visible light region of the electromagnetic spectrum?
The property that determines a visible light region of the electromagnetic spectrum is wavelength. Visible light has wavelengths ranging from about 400 to 700 nanometers, with shorter wavelengths corresponding to violet light and longer wavelengths corresponding to red light.
What energy does the electromagnetic spectrum make?
The electromagnetic spectrum consists of a range of energies, from low-energy radio waves to high-energy gamma rays. This spectrum includes various types of energy, such as visible light, infrared radiation, ultraviolet light, X-rays, and microwaves, each having specific properties and interactions with matter.
The solar energy you are referring to is called infrared radiation. It has longer wavelengths than visible red light and is felt as heat when it is absorbed by an object.
Does radiation move faster through a gas than a solid or liquid?
Radiation moves at the speed of light in a vacuum (approximately 299,792 kilometers per second). In a solid or liquid medium, the speed of radiation is slightly slower due to interactions with the medium's atoms or molecules. In a gas, radiation can travel faster compared to a solid or liquid but still slower than in a vacuum due to lower interaction with gas particles.
Which region has the longer wavelength-visible light or infrared?
Infrared light has longer wavelengths than visible light. Visible light ranges from about 400-700 nanometers in wavelength, while infrared light ranges from about 700 nanometers to 1 millimeter. This difference in wavelength determines how these types of light interact with matter and are perceived by our eyes.
When a crystal absorbs a photon, that energy becomes part of the crystal. When that same crystal releases a photon, that photon is taking energy away from the crystal.
The Stokes Shift is a measure of the difference in wavelength (and thus energy) of photons absorbed by a crystal and then immediately re-emitted by that same crystal. The energy shift between the two photons is an indication of how much energy has been permanently absorbed by the crystal in the form of heat.
What reaches the earth first x-ray radiation or visible light?
From the same event on the same source both should arrive at the same time, unless delayed by an intervening medium.
What electromagnetic waves does a fire give off?
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).
Can the storage in solar panels cause headaches and ringing ears?
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.
What are the possible negative effects of infra red waves non ionising radiations?
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.
Do supernovas emit gamma rays?
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.
What could exposure to ionizing radiation cause?
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.
How much of the electromagnetic spectrum can your eye detect as light?
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.
Which is the most penetrating rays x-rays or gamma rays?
Gamma rays are the most penetration rays because of its shortest wave length...
What is the formula for electromagnetic radiation?
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.
What is the wavelength in nm of a light in a vacuum that has a frequency of 40 x 10 14 Hz?
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.
Why are X-rays used in the preference of alpha beta and gamma radiation?
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.
What is the infrared radiation emitted from a candle?
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.
What metals reflects electromagnetic radiation?
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.
