The method used to perform the experiment. 1. Insert the tray into the desired location. Fill out a trays, water levels stood at about 1.5-4 cm .NN2 water level is regularly standing trays as well. 2 plug the lamp, lighting, and dc 12/v.ac into motor 24 volt 0 dc.powersupply.-3. 3. the demonstration in front of the waves (about the origin of waves length in a straight line.) Adjusting the touch surfaces beam.to phi aluminum sheet evenly throughout the length of the axes rotate knock. Move the origin (2) above the water level (beam on a surface vibration will not cause the tap.) Swap the power supply to the dc motor vibration caused by frequencywaves waves by increasing or decreasing the voltage of the power source. 4 the curve the wave face demo (at the beginning of the wave generator) Move the bar to a higher level. Rotate the pedal tap stem as waves knock at the end of the stem touch the surface (either one or two of the experiments of theneeds) Switch dc power supply to the motor causing the vibration. A frequency by adjusting the voltage of the power source. 5 experiment on reflection of waves: waves reflecting surfaces are placed in the tray of the affected water.to. Slow rhythmic tapping fingers attached to the lever in order to cause the beat of the pulse. Waves in a straight line to move the reflective wave fall and observing the events reflect the wave changeanother four times in each of the performing and observing the wave events that occur and the waves reflect. , And then save the resulting from the reflection wave curve experiment.replacing (convex and concave) surfaces instead of simply phiosathon. Experiment in the lab would notice. Wave events that occur and the waves reflected from the trial at any time, save the results of experiments carried out with the same time to supply dc.power. In order to achieve continuous wave Notice the wave events that occur and the waves reflect and record. The result of the completion of the above experiment experimentupon the shift as the earthquake waves that come knocking. As one of a similar experiment using a linear RF. 6 experiments on refraction of waves: using heavy objects that are placed in trays of water to drown.add water on the tray and so on. The first experiments using the throughout.sheets object, the object that has the same thick paste to a different angle in the direction of motion of the wave waveexperiments wave front line observing different angles of incidence rather than an object that has a slope that is very large, and as long as working closely with innovative styling.The original. First place objects, facing deep water front (rear end) facing the angle.different object in the direction of motion of the wave, the wave page. Observe the characteristics of waves. Angle of incidence that varies from trial to trial, facing the object, and then insert the. style.shallow water (deep water back there is the face of the object at different angles to the direction the wave is the original wave observed.view and record results of experiments. 7 on the lens. Place an object or narrow (space) Middle tray waves.and born shown.4switch page spectrum that will obstruct the work of the wave, the first screen that wavelength of much. Wave experiment to observe the shape of the waves through the curtain, and then save the resulting ofwas later changed the width of the channel gradually more and more wider than the width of a wavelength. Continue using the trial to adjust the width of each of the individual channels to save the results.experiments to compare the results and conclusions of the trial. . 8 the principle of Huygens ' s: treat it like 7 but made waves with multiple channels (channels) is a partition separates the wave function is shown.switch. Notice the front wave through scenes before and after the accident. Save the results of experiment and experimental results. 9 waves or wave, the wave front is a reflection of the orientation media bottom of surge generator surge wave linear page. in frequency as it appears in the tray, Drawing.the or come to the wave of distancethe perpendicular to that extent. until the waves with the (original). Standing wave shows that the constant nausea, length.during the first pitch. Highlighted for the first time, or a dark phase is highlighted. 's next/2 ( = wavelength waves of experiments) antinode.the dark circles highlighted as nodes of the wave data from the trial.
