What is invisible heat radiation?
Invisible heat radiation refers to a form of electromagnetic radiation that is emitted by all objects with a temperature above absolute zero. This radiation is not visible to the human eye but can be felt as heat. Examples include infrared radiation and microwave radiation.
Examples of infra-red radiation?
Some common examples of infrared radiation include heat emitted by a fireplace, the warmth felt from sunlight, and the heat given off by the human body. Additionally, infrared radiation is used in various technologies such as infrared cameras for night vision, remote controls, and in thermal imaging devices.
How can you tell if solar energy has heated Earth or if energy from the sun has transferred to Earth?
Solar energy heats the Earth through radiation, causing an overall increase in temperature. The transfer of energy from the sun to Earth occurs through various processes, such as radiation, conduction, and convection. Monitoring temperature changes and energy exchange can help scientists distinguish between the two.
What is a star's emission spectrum?
The emission spectrum of a star is the spectrum of frequencies for emitted electromagnetic radiation during the transition of an atom's electrons from a high-energy state to a low-energy state. The emission spectrum can differ depending on the temperature and composition of the star.
Which form of electromagnetic radiation has highest level of energy how can you tell?
Energy (E) of photons of electromagnetic radiation is given by Planck's equation ..E = hf .. h = Planck constant (6.625^-34 Js), f = frequency (Hz)So E is proportional to frequency .. radiation with the highest frequency is Gamma
Why does a star's color tell you about the star?
A star's color indicates its surface temperature, with hotter stars appearing blue or white, while cooler stars appear red or orange. This color variation is a result of blackbody radiation, where temperature affects the wavelength of light emitted. Additionally, a star's color can provide insights into its age, composition, and evolutionary stage, helping astronomers understand its lifecycle and the broader dynamics of the universe.

Why do people working around radioactive waste in a radioactive storage facility wear badges that contain strips of photographic film?
The film in the badges changes colour when radiation hits it. By looking at the badges, the people wearing them can tell how much radiation they have been exposed to. They have different strips of film for different types of radiation, so they are not only able to tell how much radiation someone has been exposed to, but also what type of radiation. Its basically a safety measure to ensure that workers are not exposed to excessive levels of radiation emitted from the waste.
In the tv show vampire diaries what was Stefans reaction Elena finding out he was a vampire?
He just wanted her to give him a chance to explain, and didn't want her to tell anyone.
How do you tell how to tell how strong a volcanic eruption will be?
you find the heat and pressure of the radiation of the volcano.
How can a film badge tell which type of radiation is being absorbed?
Different layers of materials have different absorbances for radiation.
How can you determine if your Toyota scion xd is contaminated by radiation?
Why would you suspect it is contaminated with radiation? A geiger counter will tell you if it is.
Examples of infra-red radiation?

Additionally, infrared radiation is used in various technologies such as infrared cameras for night vision, remote controls, and in thermal imaging devices.
Where does background radiation originate?
Background radiation can come from all sorts of sources, some natural, some man-made.Examples include...cosmic rays from spaceradon gas emitted from the earth's crustelectromagnetic radiation from a number of possible sourcesatomic radiation from nuclear substances.For much more information see Related links below this box.
How does radiation transfer heat in the atmosphere?
Well to tell you the truth I have no clue I hope this was helpful.
How can you tell which atoms are stable?
The atoms are stable when having the ratio of neutrons to protons that lie on the atom stability line. These stable atoms do not emit radiation as alpha, beta, neutron, or gamma radiation.
Why do chihuahuas hate microwaves?
Their natural instincts tell then to stay away from the radiation emitting food to rubber machine.
