Physics of Color Vision and Color Blindness Essay example -- physics e

What is Color? To understand what color is, we first need to understand what light is. Light, as perceived by humans, is simply electromagnetic radiation with wavelengths between roughly 380 nm and 740 nm. Wavelengths below 380 nm and above 740 nm cannot be seem by the human eye. Electromagnetic radiation with a wavelength just below 380 nm is known as ultraviolet radiation. Electromagnetic radiation with a wavelength just above 740 nm is known as infrared radiation. The sun, black lights and fluorescent lamps are all sources of ultraviolet light. Heat is a source of infrared radiation, which is how thermal vision works. Electromagnetic radiation between the wavelengths of 380 nm and 740 nm constitute light and the human color-vision spectrum. There is evidence that other animals, namely insects and birds, have a color-vision spectrum that extends further into the ultraviolet range. Evolutionary factors greatly influence the development of color vision in different animals and species. Although the human color-vision spectrum is continuous, it can be broken down into discrete ranges of colors which are then labeled with specific names. Surfaces gain the appearance of color based on their reflection and absorption of different wavelengths of light. A surface that reflects all wavelengths of light appears to be white. Conversely, a surface that absorbs all wavelengths of light appears to be black (and also heats up as a consequence of absorbing this electromagnetic radiation). If a surface does not reflect all wavelengths of light equally, it will appear as a color in the human color-vision spectrum. Color Vision Color vision is a highly-debated gray area that lies somewhere between physics and psychology. As we h... ... apart. Be afraid to drive near me because I'm a bad driver. I didn't feel so smart in kindergarten. Between the color flash-card tests and the green suns I was apparently drawing with my crayons, kindergarten was not exactly the high-point of my life. Thank goodness for those little brown spots on bananas! They say that bananas go from being green to yellow when they ripen. To me, they go from being yellow to yellow, so I only trust the spots. Bananas rule! That one game of soccer... When I was a kid, I played in this one game of soccer where my team had green jerseys and the opponents had yellow jerseys. Somewhere in the middle of this game, the sun started shining in such a way that I could not tell the jerseys apart anymore. This was the worst game of soccer I've played in my life. I quit soccer and took up bowling. I showed them.

(2010 Honda Civic) While looking up articles, there were not any that said the Honda Civic had uncomfortable seating.However, any article that says the seats are uncomfortable could be wrong. It does not matter how the seats feel to anybody else, it is how the seats feel to each individual that matters. Gas prices are outrageous; so why not get a gas saving car? Living in a hilly/mountain area the gas mileage of a car will not be as good as what it could be. The gas mileage of a car will be better in an area that has a lot of flat land where a person has to drive a little ways to get where they are going. Gas mileage is that way with any vehicle, but when driving around and topping and starting every five minutes, it will use more gas than just driving around for about thirty minutes. The Honda Civic’s gas mileage for the city and highway is approximately twenty-five and thirty-six, while the Ford Focus’s city and highway gas mileage is approximately twenty-four and thirty-five. (2010 Honda Civic) There is barely any difference in the two cars gas mileage, so which ever car a person picks they will get good gas mileage. Most everybody likes a deal when buying anything.

Everybody should make sure that they have a good warranty so if anything messes up on your new car; it can be fixed for cheaper than what it would be without warranty. The Honda Civic and the Ford Focus warranties are for three years or 36,000 miles. Both have a power train warranty of five years or 60,000 mile s. Also, both cars have a rust-through warranty of five years or unlimited miles and they both have a roadside aid warranty of three years or 36,000 miles. Remember all the warranties say the year or mile, but mean whichever one comes first. Compare Cars) Some cars do not come with very good warranty, but the car needs to come with as much warranty as necessary to suit your needs. If it does not, then that car is simply not the right car to buy. When buying a car, make sure to evaluate the performance specifications that are on the car. How the car performs is important to just about everybody because nobody wants their new car to mess up on them right after they buy it. The Ford Focus is almost the same size as the Honda Civic, but the Ford Focus is just a bit larger than the Honda Civic. 2010 Honda Civic vs) The Honda Civic and the Ford Focus both are front wheel drive and four wheel drive power brakes.

The Honda Civic has fifteen inch tires on the front and rear tires (2010 Honda Civic Hybrid – 4dr), while the Ford Focus has tires that are seventeen inches on the front and rear tires. 2010 Ford Focus-4dr) Here, the only reason that the Ford Focus is better than the Honda Civic is because of the power rack and electric rack. My family has never owned a car that has not had power rack and pinion steering, so that is why we would prefer the Ford Focus over the Honda Civic. Safety in a vehicle means a person’s life. Before buying a car, check out the safety features that vehicle has on it. The safety features in a vehicle is very important to everybody. So here is a little bit about these two car s safety.The Honda Civic and the Ford Focus both have front side airbags, curtain side airbags, antilock brake system, and antiskid system. The Honda Civic has traction control that the Ford Focus does not have. (2010 Ford Focus: Overview) The Ford Focus has dual front airbags and tire-pressure monitor that the Honda Civic does not have. (2010 Honda Civic: Overview) A tire-pressure monitor does help from having a blow out and the dual front airbags would probably make the passenger feel safer. Comparing, what the Honda Civic has over the Ford Focus makes the Ford Focus better.Buying a new car can be very overwhelming. Researching a few kinds of cars helps to narrow it down to the two cars you are leaning more towards purchasing and can make it a lot easier. The Ford Focus Sedan is better because of all the points made in this paper. Although the Honda Civic Hybrid is a good car too, the Ford Focus Sedan is what is needed to suit my family’s needs. This paper hopefully helped somebody make a decision on buying one of these types of cars or helped somebody out on what to look for when buying a new vehicle.
