Why are concave mirrors used in telescopes?Reflecting Telescopes:Reflecting telescopes quickly replaced refracting telescopes for professional observatories as it became apparent that their mirror could be manu
Unfortunately, gratings suffer from the aberrations of concave mirrors and others due to their diffraction capabilities. Working in the Rowland conditions definitively limits the imaging quality of the instruments. The major aberration here is astigmatism. This aberration can be tolerated with a monochroma...
You can also buy what HMRC calls "cyclists' safety equipment" which could include helmets, bells, lights, mirrors, locks, and reflective clothing. The total amount you could spend was previously capped at £1,000, but as of June 2019 this restriction has been removed. Why shou...
Why are light touch receptors found at the skin's surface? Why do mirrors reflect backwards? Why is glass an amorphous solid? Why does water form droplets? Why is there no refraction at a 90-degree angle? Why is the reflective index of glass greater than the reflective index of water?
Additionally, developmental stories can serve as reflective mirrors for beginning and experienced therapists to observe themselves in, encouraging self-reflective practice that has the potential to enrich this practice.Guthrie, Andrew
Mirrors are used to test self-recognition in humans and animals. Researchers infer that if subjects can tell that the image on the reflective surface is in fact them, then they have developed a cognitive sense of self. Children learn to recognize themselves in the mirror at around 20 mo...
Other Uses:Silver’s reflective properties are harnessed in mirrors and coatings, enhancing image quality and light. Inchemical catalysts, silver speeds up reactions, with the chemical industry using around5%of global silver supply. Inwater purification systems, it ensures clean and safe water, demons...
Blind spots. Motorcycles tend to be smaller and harder to notice than mainstream vehicles, which makes them even more vulnerable to blind spots. Drivers of conventional vehicles may focus on the road and check their mirrors often, but if they aren’t specifically looking for motorcycles, they ma...
Similar to the intention, all other TPB variables are measured on seven point Likert-style scales. The way the questions are operationalised closely follows Ajzen's (2006) own suggestions as well as other applications of the theory (in other fields). The selection of indicators mirrors typical...
In most green frogs, sunlight penetrates through the skin to the little mirrors in theiridophores iridophores Iridophores and leucophores Iridophores, sometimes also called guanophores, are chromatophores thatreflect light using plates of crystalline chemochromes made from guanine. When illuminated th...
