Speed of light

Refraction of light is the change in direction of a wave passing from one medium to another caused by its change in speed. This is the bending or breaking that occurs throughout this lab. Learning about refraction is the main purpose of this lab and is explained through four separate experiments. The first experiment includes a medium size glass, water, and a pencil. The first step of this section was to fill the glass to two-thirds full of water. Then take the pencil and circle it around both…

involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give off light to jump downwards to lower energy levels. Any atom will absorb and release the same frequencies of electromagnetic radiation. In an emission spectrum, you…

It is sad that there are so many taboos they must face every day. There was one quote from a speed dater named Addie (2014) that really struck me “I have to be out there. I haven’t changed. Just because I’m older, I have not changed. The essence of who I am is always there.” Even though this is a simple quote it really is the truth. No matter how…

the cyclops, Odysseus says “If I could take your life I would take your time away, and hurl you down to hell” (9:438-440). The Flash’s challenges also become more difficult. Barry’s challenges are comprised of fighting off criminals with his super speed, falling in love with Iris who loves Eddie Thawne, attacking metahumans that are different from himself, going back in time to choose whether or not to save his mother, and protect his Earth from Zoom, a speedster faster than Barry, who wants to…

The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…

Borealis? As electrically charged particle collisions from the sun enter the planet’s atmosphere and encounter atmospheric gases, a light show spectacle is displayed around the magnetic poles of the earth. The aurora phenomenon occurs at poles of both the northern and southern hemispheres of the planet. They are most commonly known as the “Northern Lights” and “Southern Lights”- Aurora Borealis and Aurora Australis, respectively. However, since the southern aurora occurs in the southern pole of…

solution had to be diluted to get the lower number. The maximum time to dilute solution in this experiment was 2. According to the Beer-Lambert Law, the absorbance changes correspond to the concentration. It expresses the relationship between the light absorbance and concentration. As the absorbance increases, the concentration also increases. The equation of the baseline is also the Beer-Lambert equation. The coordinate…

Introduction How can creatures that don’t have eyes, and ears tell if a predator is nearby? We will be looking in depth into the predation of Periwinkles (Littoraria irrorata) and the blue crab (Callinectes sapidus). What are periwinkles? Whats the reaction and relationship between the two species. How can one species detect the other? Once we explore the our creatures we will then conduct an experiment to test if there are any notable difference in the reactions of the periwinkles in the…
