Is bioluminescence the same thing as photophores?
Bioluminescence is not the same as photophores.Photophores are light emitting organs that are found on marine animals such as cephalopods and certain fishes.Bioluminescence is the production and emission of light by a living organism. Bioluminescence is a form of chemiluminesence where energy is released due to a chemical reaction in the form of light. It is found in many vertebrates, invertebrates, fungi, microorganisms and terrestrial animals.
Is there radiation in glow sticks?
Glow sticks do not contain radiation. They produce light through a chemical reaction that emits light in the visible spectrum, typically involving a combination of hydrogen peroxide, a fluorescent dye, and a phenyl oxalate ester. They are safe to use as directed.
What radiates its own light?
Anything that gives off light can be said to radiate its own light. There are different types of light emission: incadescence, flourescence, chemiluminesence, and electroluminescence. Of all of these methods, only chemiluminescence is self contained - all other forms of light emission require an external source of energy. Only chemoluminescent materials, therefore, can be said to radiate their own light..Glow sticks are an example of chemoluminescent materials. Two chemicals in the stick are kept separate by a membrane. When the stick is bent sharply, the membrane ruptures, and allows the two solutions to mix and interact, thereby creating a chemoluminescent reaction..Bioluminescence is a naturally occurring example of chemoluminescence. Fireflies have light emitting organs that combine an enzyme (luciferase) with a pigment (luciferin), and the combination of these chemicals results in a chemoluminescent reaction..One could also argue that the sun, and all stars, are also self contained, and they therefore also radiate their own light.
