Can blood glow?
Blood itself does not glow in the dark; however, it can appear to glow under certain conditions, such as when exposed to ultraviolet (UV) light due to the presence of certain compounds. Additionally, bioluminescent organisms, like some jellyfish, can produce light, and if their blood interacts with certain chemicals, it may exhibit glowing properties. In a laboratory setting, certain dyes or reactions can also cause blood to fluoresce.
How does sodalite glow?
Sodalite can exhibit a glow under ultraviolet (UV) light due to the presence of certain minerals and impurities within its structure. When exposed to UV light, some of these impurities can fluoresce, emitting visible light in response. This phenomenon is often seen in specific varieties of sodalite, enhancing its visual appeal and making it popular in decorative applications. However, the glow is not inherent to all sodalite stones and depends on their specific mineral composition.
How do scientist use the electromagnet spectrum to determine the temperature of a star?
Anything with heat emits electromagnetic radiation, even if it is only in the infrared (IR) wavelengths. As matter gets hotter, it tends to change color. For example, if you've ever seen glowing metal at a steel mill or in a blacksmith shop (like on a movie) you notice hot metal glows red, hotter metal glows yellow, and even hotter metal glows white. If you apply this concept to stars, you can start to see that by measuring the color, you are also measuring the temperature - how? because a star at a certain temperature glows a certain color. Reds are the "cooler" stars (still very hot) and blues are the hottest stars - at least when we are talking visible spectrum.
What are the top 20 hardest substances known to man?
The top hardest substances known to man include diamonds, which are made of carbon and ranked highest on the Mohs scale, followed by materials like boron nitride, wurtzite boron nitride, and aggregated diamond nanorods. Other notable hard materials include corundum (sapphire and ruby), cubic boron nitride, and materials like moissanite and various forms of carbon such as graphene and carbon nanotubes. Additionally, certain synthetic materials like diamond-like carbon and various superhard ceramics contribute to the list of the hardest substances. These materials are often used in industrial applications requiring extreme durability and abrasion resistance.
What are two pieces of evidence of the big bang and that the universe is expanding?
1) Red shift seen in all distant galaxies, whose size is propotional to the galaxy's distance from us. 2) Existence, isotropy, and spectrum of the cosmic microwave background radiation.
Electromagnetic radiation causes certain substanced to fluoresce?
Yes. UV radiation causes phosphor to fluoresce in fluorescent light bulbs.
Which one of the following types of electromagnetic radiation causes certain substance to floursce?
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Which one of the following types of electromagnetic radiation causes certain substances to fluoresce a ultraviolet rays b infrared waves c x rays d cosmic rays?

Which one of the following types of electromagnetic radiation causes certain substances to fluoresce ultraviolet rays infrared waves x rays or cosmic rays?
Exposure to radiation in the ultraviolet region is the most common way of causing fluorescence, but not the only way. Exposure to enough radiation for one electron to absorb two photons can cause fluorescence.
What does fluoresce mean?
Fluoresce means to emit light or glow when exposed to ultraviolet radiation or certain wavelengths of light. This phenomenon is commonly seen in certain substances like fluorescent markers, minerals, or biological materials.
What does fluorecent mean?
It generally means "glowing" - certain elements "fluoresce" (give off a visible light) when hit by electromagnetic radiation, even when the radiation itself is invisible (e.g. UV light). An example is in fluorescent lighting tubes where mercury vapor is electrified to cause a phosphor coating to fluoresce. A slower process called phosphorescence occurs where glow-in-the-dark stickers absorb light and radiate it back slowly as a greenish glow.
Exposing certain substances to radiation is known as?
irradiation
How does the earth's atmosphere protect living organism from certain types of electromagnetic radiation?
be far from those radiation
Is light a kind of radiation?
Yes, light is a type of electromagnetic radiation that is visible to the human eye. It falls within a certain range of wavelengths on the electromagnetic spectrum.
The Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum?
Yes, Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum, such as most ultraviolet radiation and some infrared radiation, before they reach the surface. This filtering is important for protecting life on Earth from harmful radiation.
Where can you find radioactive symbol?
in certain types of radioactive decay processes. it is not electromagnetic radiation.
Do black lights reveal the presence of germs?
Black lights do not reveal the presence of germs. They are used to detect certain substances that fluoresce under ultraviolet light, but they do not specifically indicate the presence of germs.
