Chapter 9 Essay Question and News Article Part A: Describe how it is different from visible light. What emits IR? Can animals use it? Explains how emission of IR sometimes “wastes” energy. Give examples showing how IR is used in modern technology. Infrared radiation also called IR, is a measure of the region on the electromagnetic spectrum. All radiation can be found on the electromagnetic spectrum. The main thing that makes visible light different than visible light is the frequency/ energy of that light. Visible light is wave frequencies are much higher than the frequencies of Infrared radiation. Meaning that visible light uses more energy per photon than infrared radiation needs. While warm-blooded animals are not able to see Infrared radiation, some cold-blood animals have adapted over the years to be able to. Some snakes, blood-sucking insects, fish and frogs are able to use IR for many different things. Snakes use their use of seeing IR to detect preyby relying off their body heat. Some blood-sucking insects like mosquitoes are also able to use IR to find food. They are able to see the body heat coming off of an animal or person, navigate towards them then feed of of them. There are some fish that carry and enzyme that allows their visual system to be able to infrared radiation, which in turn helps them find their food and their way through the water. There are many things that emit Infrared radiation. Because IR is typically used for heating things, it does sometimes waste energy. When you heat things not all of the energy goes straight to that object, some is transferred into other objects or the radiation is just not needed. Because the radiation is not transferred directly into objects there can not be an 100% guarantee that the energy will be needed. Infrared radiation is mostly used for heating objects because it ismuch easier for scientists to create a higher level of Infrared radiation than it is for then to create high intensity light. In modern day technology, Infrared radiation is used to detect the difference of heat in objects. It is also used to keep things warm. For example, IR is used to heat food in buffets with a special lamp. It is also sometimes put in tanks for certain amphibians to warm them. Part B: Read and find an article on physics or technology from some serious website. Give the link to that article, and summarize the article, drawing connections to class and/or explaining what you do not understand about the article. Recently it has been determined by scientists, at the Center for Quantum Nanoscience which is a sector within the Institute for Basic Science, that by packing two atoms extremely close together fragile quantum properties are much more protected than they are with just one atom. This experiment was conducted by making magnetisms from a single atom the basis of the whole experiment. From there the scientists and researchers were able to pack the two atoms together and make the scientific breakthrough about protecting quantum properties. This experiment is extremely reliant on the spin, another word for the magnetism of one single atom, it was discovered that actually bringing the two atoms super close together helps protect not onlythe positions of the spins but the state of the spins as well. This information that as discovered bythese researchers and scientists will be used to not only improve the already existing quantum properties, but explore the nanostructures of these atoms. One thing that I am curious about is these scientists are surprised that having two atoms to protect the quantum properties is better than on. It is universally known that when it comes to protection more in always better. So my question is why did it take until now for these scientists to experiment with this. Is it because thatuntil know the technology hasn’t been available or is just because scientist have not experimented with it until now?Part A:Lucas, Jim. “What Is Infrared?” LiveScience, Purch, 26 Mar. 2015, www.livescience.com/50260-infrared-radiation.html.Part B:Institute for Basic Science. “A Two-Atom Quantum Duet.” Phys.org - News and Articles on Science and Technology, Phys.org, 9 Nov. 2018,
