Summary
Single-Slit Diffraction and Interference Introduction Light can be bent from its ordinary straight-line path by means of reflection, refraction, as well as diffraction. Thus, “diffraction is the bending of a wave by means other than reflection or refraction” (Wilson & Hernandez 2009, p.471)…

Thus, when monochromatic light passes through a single slit, it flares out, producing a single-slit interference or diffraction pattern on the screen. The diffraction pattern has a bright central region, which is surrounded by symmetrically distributed less intense regions. These bright bands are the ‘maxima’ or areas of constructive interference, interspersed by the ‘minima’ or dark regions of destructive interference. Thesis Statement: This paper will describe single-slit diffraction and interference. Single-Slit Diffraction and Interference A plane wave of light travels in a straight line; so when such a wave passes through a rectangular slit, one may expect it to fall on a distant screen in the form of a bright rectangle with sharp edges. However, the process of diffraction of light through the single-slit causes the interference or diffraction pattern formed on the screen to have blurred edges with faint lines of bright and dark, where some light has spread into the shadow. The light wave spreading out from the slit is actually the interference effect termed as diffraction. As a result of diffraction, the light’s intensity is not uniform on the screen, and it extends into the shadow where it appears as secondary maxima. Between bright places in the shadow there are dark places termed intensity minima, where there is no light. According to Holbrow, Lloyd, Amato et al (2010), this is to be expected, taking a single slit of finite width b as two slits of width b/2 with no separation between them. “There might be interference between the light wavefronts coming from these two different halves of the slit” (Holbrow et al 2010, p.313). By considering the slit of width b to be composed of narrower slits, the occurrence of the intensity minima of the Interference or diffraction pattern can be calculated. Serway and Vuille (2006) reiterate that slits cannot be assumed to have negligible widths acting as line sources of light. On the other hand, their non-zero widths form the basis for understanding the nature of the Fraunhofer Diffraction Pattern produced by a single slit. Further, “according to Huygens’ principle, each portion of the slit acts as a source of waves” (Serway & Vuille 2006, p.638). A single slit diffraction pattern is formed when light passes through a single slit whose width w is on the order of the wavelength of the light. Huygen’s principle states that each part of the slit can be considered as an emitter of waves. “All these waves interfere to produce the diffraction pattern” (Physics, 2012). In the diagram (Fig.1) below is seen a slit of width w, through which light is passing through. Fig.1. Single-Split Diffraction and Interference: Direction of the Light Wave (Physics, 2012) Destructive interference may occur between the ray at the top edge (ray 1) and the middle ray (ray 5). If so, the same occurs between rays 2 and 6, between 3 and 7, and b between 4 and 8. Thus, light from one-half of the single slit interferes destructively and cancels out light from the other half. “Ray 1 and ray 5 are half a wavelength out of phase if ray 5 must travel one-half wavelength further than ray 1” (Physics, 2012).

Single Parenting
...? Type Type Your Type 18 May Single Parenting What Is Single Parenting? The meaning of single parenting is vital in developing an opinion about this phenomenon. A single parent family might be described as a family living together in a home where only one parent is present. This family, obviously, has one or more children and either the parents or any one of them is responsible for the kid(s). This situation can be reached with divorce, separation or break up after the relation without marriage. Though single parent families started originating in the early 1950's, they were at their peak somewhere around the late 1980's and 1990's. The main cause of a...

Single slit diffraction & double slit interference
...Experiment 3: Single slit diffraction & double slit interference. introduction Diffraction arises from the way in which waves propagate as described by the Huygens-Fresnel principle. The wave propagates by considering every point on a wavefront as a point source for a secondary wave. These secondary waves recombined and subsequently propagate forming the new wavefront. Interference occur when waves are added together, their sum is determined by the phase and the amplitude of the individual waves. The summed amplitude of the waves can have any value between zero and the sum of the...

...Running head: Single parents and deviant behavior Introduction It is very difficult to fully understand the development of human beings without considering the significance of family in a child's growth. The family institution plays a crucial role in a child's development; it is the basic unit that is responsible for nurturing the processes of socialization among the children. Traditionally, families constituting two parents have been considered to be the best in offering a child good parenthood, as they offer a good environment for the development of the child as compared to families of single mothers or fathers. There are some arguments that suggest that children usually try to model themselves with...

Refraction/diffraction at coastal structures
.....”). Water waves that have undergone diffraction and have bent into the lee side of the island can interfere there and produce steep hazardous seas. Wave refraction is the process in which water waves bend as they reach shallow water near the shore, due to a change in wave velocity. The wave velocity decreases when the wave base hits the ocean bottom. Since the wave in general is approaching the shore from an angle, the wave base on one side of the wave touches the bottom before the other side. This causes the wave to bend. The part of the wave crest farther out to sea in deeper water moves faster than the part of the wave crest closer to shore that has reached shallow water. The deep water part of the...

Coherent Diffraction Imaging
...in crystallography, the phase (and equivalently f(x)) can be retrieved by measurement of | F(u) | with the known constraint that f(x) is real and non-negative: f(x) 0. This is a case of a single intensity measurement. As for coherent diffraction imaging, Guizar-Sicairos & Fienup (2008) argue that because of coherent illumination of an object the image f(x) is often complex valued (so non-negativity constraint is not applicable). It makes the phase retrieval problem in CDI much more difficult and requires the use of reliable and efficient techniques for dealing with the problem. 2. Iterative phase reconstruction algorithms A widely adopted and successful approach to solve the image-reconstruction...

But not all soldiers get the support that they need. While outwardly tough and strong, a soldier’s life is always made easier by knowing that someone is waiting for them at home, a loving wife or family. For single soldiers, however, this aspect of their life is missing. As a society we need to think long and hard about single soldiers and help develop a system that is more responsive to their needs. But first we need to look more closely at the lives and challenges faced by single soldiers. The truth...

Interference Colors
... Interference Colors An interference color is a color that is exhibited by a segment of an anisotropic mineral under cross-polarized light. Impedance delivers this color between the two beams created as light goes through an anisotropic mineral, the quick beam, and the moderate beam. Intervention between the two beams produces colors diverse from the source light by productive impedance since the period of the fast beam is moved with respect to the moderate beam. The act of light slowing down as it passes through a substance is measured using a number referred to as the index of reflection. Interference colors are thus an effect that emanates because different substances have different index of reflection (Ulery, & Drees 185... )....
