Infrared

As our society becomes more technologically advanced, many things advance with it. This includes criminal investigations, which can be aided by infrared spectroscopy. IR spectroscopy deals with the infrared region of the electromagnetic spectrum. This region is light with a longer wavelength and lower frequency than visible light. (Wikipedia) IR Spectroscopy is a method to identify substances based on their absorption of infrared wavelengths. It is a study of how the molecules of substances can absorb infrared radiation and convert it into heat. (Cole) A machine called an infrared spectrometer applies infrared rays to a substance to record the number of wavelengths absorbed by said substance. (Cole) This works because of covalent bonds within substances. These bonds can be viewed as stiff springs that can be stretched and bent. (Ki) They vibrate at different amounts of energy and at a frequency that depends on the mass of the atom and strength of the bond. (Ki) the mass is larger, the frequency is lower. Also, stronger bonds yield higher frequencies. (Ki)…

only the black line. Object following robot: Finally, lets create a obstacle following robot. As like the other switch robots, for object following robot, we need to place the sensors at the front side of the robot. each robot creation, will be involved with a certain concept from our general Physics and some times, we experience them in our daily routine too, but we couldn’t relate them. Now, let’s try understand the concepts involved in this robot creation. In this robot, we have implemented 4…

the Kinect’s algorithms will try to guess the current po- sition of the occluded limb. Furthermore this occlusion would also disallow the control this limb. A suitable solution was presented by Cui, Schuon, Chan, Thrun, and Theobalt, 2010, combining multiple Kinect’s, tracking the subject from different perspectives. It should be noted that combining multiple time-of-flight (TOF) cameras in realtime does not go with- out penalty. Should the infrared points, sent out by multiple Kinects (See…

start by talking about the thermal radiation. Thermal radiation is energy where it transfers by the emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is called,” Stefan Boltzmann Law.”In 1879, it empirically obtained by Josef Stefan. In 1884, it was obtained theoretically…

What types of light can a light sensing BlueBot detect? Lights are used for many everyday tasks, and many days they go unnoticed. There are many types of lights, such as Ultraviolet, Infrared, fluorescent, and LED lights, and they all can do different things. Ultraviolet light can be used as a way to light up certain types of clothing, or it can be used to sterilize food. Infrared light is mainly used as a way to heat up food, or as a shorter wavelength to control household items, such as…

According to Fankhauser et al. (2015), there is a general consensus that the first version of Microsoft Kinect is a depth sensor that quickly returns high-resolution depth images for a low cost. The original version of the Kinect 3D camera uses a real-time algorithm to calculate distance by triangulation using randomly-projected infrared light beams (Chen, Yue, Wu, & Wang, 2014), and presents point-like depth readings in the form of point clouds (Stefanczyk et al., 2013). According to…

What is global warming? a. Global warming is the increase in the temperature of the entire earth. i. As the temperature increases the atmosphere is being damaged by the increased levels of carbon dioxide (CO2) produced by the greenhouse effect. ii. The greenhouse effect is the trapping of the sun’s warmth in the planet’s lower atmosphere due to the greater clarity, or transparency, of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface. …

Methods Column chromatography was set up using a 60 ml syringe clamped to a ring stand. The syringe was plugged using a small amount of cotton. An Erlenmeyer flask was placed underneath the column to collect any excess material. Eleven 20 ml vials were labeled numbers 1 through 11. Silica gel was measured to 42 ml using a graduated cylinder and then moved into a 150 ml beaker. A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. The slurry was stirred for…

of CO2 into the atmosphere and that gas captures the infrared red which causes global warming Three scientists in the 19 century have studied infrared radiation and its effects on global warming. A German astronomer, Frederick William Herschel, discovered infrared radiation on February 11, 1800. Herschel used a prism to separate the different wavelengths and noticed that the wavelength with the highest temperature was beyond the red visible light portion of the visible light spectrum. This means…

from the sun is not exactly the light that comes to the earth from the sun. We see sunlight as being whitish in color, but it actually is a blend of the colors of the rainbow. The reason we see it this way has to do with the way our eyes perceive color. This is because, “Our eye contains three kinds of light-sensitive cells, each sensing a different band of colors--one band centered in the red, one in the green and one in the blue” (“(S-4) The Many Colors of Sunlight,” 2006). This is why the…
