Focal Length And Lenses Lab Report

teacher I am required to take into account both dimensions. So this became my goal and tool to use.

Alignment of the anatomical part can also affect the image. Shape distortion is when an image appears either longer or shorter based on the way it is positioned in relation to both the central ray and the image receptor; foreshortening is when the object appears shorter than it is in reality, while elongation is when the object appears longer than it truly is. When imaging a part, the long axis is intended to be placed perpendicularly to the central ray and parallel to the image receptor. Distortion happens when either the part or the central ray/image receptor are placed incorrectly. In addition, distortion can also occur due to standard divergence of the beam.

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth.  It is far more difficult (if not impossible), however, to picture this distance in the human mind.  In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, pedestrian numbers.  So long as every distance within the system of interest is scaled by the same factor, we retain the meaningful information about relative distances between objects.

2.Accommodation: the process by which the eye's lens changes shape to focus near or far images on the retina.

One frame from each camera is pulled into the program and then rectified based on calibration of each camera. The calibration process takes in the camera calibration parameters of the cameras, the rotation, and translation of the second camera in relation to the first camera. After being rectified based on the calibration, a disparity map is created. A disparity map is an intensity map that shows the measurements of

The area in question is located on the lawn between Powell Residence Hall and Weinbach Ave and across from Hale Residence Hall. The known elevation is 380’ and is located on the sidewalk outside Powell. First using the Total Station, our group gathered the information for the distances between points. With one person holding the prism reflector and another operating the Total Station, the distance between two points can be measured. Each set is measured multiple times with an average taken. The averages between points 1 and 2 is 96. 930 ft., 2 and 3 is 120.267 ft., 3 and 4 is 103.528 ft., and 4 and 1 is 99.597 ft. Next with the Total Station, the angles can be measured between points. The zero line is set, then the rod person moves clockwise to the

1)The field of view in Figure 1-2 is a factor of 100 larger than the field of view in Figure 1-1. What aspects of Figure 1-2 increased by a factor of 100 relative to Figure 1-1? Did the height increase by that amount? The diameter? The area?

Find the average distance of Pluto from the Sun. Using the same scale as Procedure B, calculate the scaled distance that Pluto should be on your model. Show your work! 5,906,376,200 / 25,000,000 = 236.25cm ~ 236 cm

The scale factor for my pre-image to my image was one-point five or one and one-half inch. By having a scale factor of one point five, the pre-image would be enlarged. If the scale factor is greater than 1, then the dilation would be an enlargement. If the scale factor would be less than 1, the dilation would be reduced smaller than the pre-image. If the scale factor would be 1 then there

There are various methods of determining the distances of stars. Some of them include the variable stars theory, parallax method, use of color and the expanding universe theory, just to mention a few. The method that is the most common and can easily be explained is parallax, which is well explained through illustration. When one holds an object high up front so that it blocks your front view and close one eye in different turns, the item appears to move in relation to the item in front. When both eyes are open one may get an idea of how far the object may be and the distance is obtained by the length of direction change, and this theory is known as parallax.

Linear perspective is a mathematical system for creating the illusion of space and distance on a flat surface. Linear perspective was first used in Florence, Italy in the 1400s by Brunelleschi, an artist and architect. However, the first person to write the rules down was Leon Battista Alberti. Many artists have developed a concept of Alberti’s system for artists to follow. Leonardo da Vinci probably learned Alberti's system while serving as an apprentice to the artist Verrocchio in Florence. (Exploring Linear Perspective)

The height and width of this optotype is designed to be five times the thickness of the stroke width and gap width, therefore the size of each critical detail is 1/5th of the overall height (Kalloniatis & Luu, 2005). Four stimulus sizes were used in the experiment as visual acuity was to be tested at four eccentricities (0˚, 20˚, 40˚ and 60˚). These four stimulus sizes were calculated using the approximate minimum angle of resolution (MAR) of each eccentricity obtained from Millodot et al.’s (1975) normal data. This value was then used to find the gap size and hence the stimulus size using a distance of 600cm. The reason for using the distance value of 600cm was because it is close to the threshold and therefore would be the starting point of stimulus presentation for each of the eccentricities. The formula used was:

The first thing I wanted to do was to estimate the approximate distance of which the

Resolution is related to the numerical aperture of the objective lens – the higher the numerical aperture, the better the resolution; and the wavelength of light passing through the lens – the shorter the wavelength, the better the resolution.
