What is the procedure in Davisson-Germer experiment?
Vigorouschemist
The Davisson-Germer experiment demonstrated the wave nature of the electron, confirming the earlier hypothesis of de Broglie. Putting wave-particle duality on a firm experimental footing, it represented a major step forward in the development of quantum mechanics. The Bragg Lawfor diffraction had been applied to x-ray diffraction, but this was the first application to particle waves.
Davisson and Germer designed and built a vacuum apparatus for the purpose of measuring the energies of electrons scattered from a metal surface. Electrons from a heated filament were accelerated by a voltage and allowed to strike the surface of nickel metal. The electron beam was directed at the nickel target, which could be rotated to observe angular dependance of the scattered electrons. Their electron detector (which was also called as a Faraday box) was mounted on an arc so that it could be rotated to observe electrons at different angles. It was a great surprise to them to find that, at certain angles there was a peak in the intensity of the scattered electron beam. This peak indicated wave behaviour for the electrons, and could be interpreted by the Bragg Law to give values for the lattice spacing in the nickel crystal.

What are Precautions for mensuration experiment?
When performing a menstruation experiment, there are several precautions that should be taken to ensure safety and accurate results. Here are some of the key precautions to keep in mind: Wear appropriate protective gear: When handling chemicals, it is important to wear appropriate protective gear, such as gloves and safety glasses, to prevent accidental exposure to the chemicals. Handle chemicals carefully: Chemicals should be handled with care and according to the instructions provided. This includes using the correct amount of chemicals, avoiding contact with skin or eyes, and keeping chemicals away from food and drink. Maintain a clean workspace: Before beginning the experiment, the workspace should be cleaned and free of any potential hazards or contaminants. Follow proper disposal procedures: After the experiment is complete, any leftover chemicals should be disposed of properly according to local regulations. Monitor and control temperature and humidity: The experiment should be conducted in a controlled environment, with temperature and humidity levels monitored and maintained as necessary to prevent interference with the experiment. Use proper measuring tools: When measuring substances or quantities, it is important to use accurate and appropriate measuring tools to ensure accurate results. Follow the experiment procedure carefully: The experiment procedure should be followed carefully and accurately to ensure the experiment is conducted correctly and the results are reliable. By following these precautions, the menstruation experiment can be conducted safely and accurately, with reliable results that can be used for research or educational purposes.
This is a factor that changes in an experiment. Proper procedure calls for testing only one of these at a time?
well the last guy who answered wasnt very smart. the REAL answer is variable. No doubt about it. Sorry, but u r not the sharpest pitch-fork in the barn! LOL

What is Procedure and aim of experiment?
The procedure of an experiment is the step-by-step sequence, usually written down, that describes what will be done during the experiment. The aim, or objective, of the experiment, is to prove or disprove the hypothesis which was formulated in order to run the experiment. Alternatively, the objective can be to measure something, such as the torque / horsepower curve of a motor as a function of input power.
What does it mean to rewrite your procedure to address the flaws in the original experiment?
Modify the experiment.
