At the same time, the lack of perfection suggests there are some possible sources of unmeasured and unwanted influence on the value of the charge-to-mass ratio. Careless error and systematic error are the two possible sources of influence in this experiment; observational errors due to a lack of brightness of the electron beam or other issues would fall under the category of careless error, while any lack of consistency or proper calibration in the apparatus would result in a systematic error.
Creating the proper environment for accurate observation, including darkening the room and using a high enough voltage in the magnetic coils (1500V) can create a situation where the electron beam is most visible, reducing the potential for careless error. Proper maintenance of the equipment being used in the experiment will help to ensure that systematic errors are reduced if not eliminated, though proper measurement and calibration remain necessary.
Regardless of the strength and the voltage intensity of the electric filed E, the electron beam remains uninfluenced. Slight curves are created in the beam due to the lack of complete uniformity in the magnetic field; as the beam interacts with the magnetic field at many points and at a certain volume in space, rather than at a single distinct point, variations in the magnetic field cause slight curves and shifts...
The electric field also lacks uniformity at and near the edges of the deflecting plates, which exacerbates these slight curvatures.
1.76 x 10 C/kg is an established and excepted value for the charge-to-mass ratio of electrons. The calculated value of the charge-to-mass ratio in this experiment is . The percentage of difference between the calculated value and the accepted value can be demonstrated by the below formula to be 96.5%:
[ (Calculated value -- " Accepted value) / (Accepted value) ] x 100%
CONCLUSION:
The difference between the calculated charge-to-mass ratio in this experiment and the accepted value for charge-to-mass ratio is 96.5%. This is a very significant difference, with the calculated value found in this experiment nowhere near the accepted value established form previous experimentation and observation. Plotting the value of I2 and V and plugging the results into the given equation can help to recalculate the charge-to-mass ration, and more importantly the experiment can be repeated to produce more data sets in order to obtain an experimental value that is closer to the established accepted value. Utilizing different pieces of equipment in the same set up would help to ensure that any faults in individual pieces f equipment are not tainting and invalidating the results of this experiment.
Properties of Light Light is one of the most basic physical phenomena. It is observed by most people on a daily basis, and even people who lack formal understanding of the properties of light have some understanding of its properties. For example, most people have seen mirrors, rainbows, and know that glasses can improve vision, though they may not understand that reflection of light explains how mirrors work, that dispersion
Dennett says that the consciousness only plays tricks with our minds and makes the experiences to be assumed to be non-physical, which in turn raises the ontological problem of non-physical existence of everything. Dennett, therefore, would seem to offer to take into consideration the small factors in detail, which eventually build up to the bigger picture of the ontological problem of hard existence, to solve the problem. I have
Solving the 1D Bin Packing Problem Using a Parallel Genetic Algorithm: A Benchmark Test The past few decades have witnessed the introduction in a wide range of technological innovations that have had an enormous impact on consumers, businesses and governmental agencies. Computer-based applications in particular have been key in facilitating the delivery of a wide range of services and information, and computer processing speeds have consistently increased incrementally. Computer processing speeds,
Real trial-based evidence shows a clear success in reduced cracking in cement which is reinforced thusly. Our research tells that these reinforces cement bodies "have aspect ratios of 500 or more and diameters - about the same size as the distance between layers in hydrated cement - so that cracks in the matrix would quickly encounter well-dispersed SWCNTs, inhibiting their growth." (Makar, 1) In order for these findings to be used in any real-world setting,
Computer Technology, The Concorde Jet Liner, And Ethics The issues of ethic in business practices in the age of increasing computer technology and the importance of managing information has come to the forefront of organizational management issues. In a society which now creates much of its wealth, not from hardwoods products, or services, but from the use of information, the integrity of that information is imperative to the ongoing well-being of
Light Energy illustrates the techniques employed by various scientists in determining the accurate value of the speed of light. This paper outlines all the methods employed by them and the grave difficulties they faced in acquiring a more accurate value. This paper also emphasizes on the importance of the value of the speed of light. Light Energy One of the fundamental concepts that is put forward for the students, who are
