Abstract

Research has been carried out about the behaviour of the micro wave when it passed the obstacle to the straight side in Fresnel diffraction. In this research the micro wave evidently crept in the straight direction and omnidirection. This condition, however, was not suitable to be applied in Fresnel diffraction to the obstacle to the straight side. As a result, there was some deviation between the results of the analysis of the data and the theory-based calculation to determine the relative intensity in a certain point by the detector/the micro wave recipient. According to the theory-based calculation, the result of the relative intensity of I/I0 in the P point that was in the geometric shadow bank was 0.25 whereas the result that were received from the analysis of the data was 0.012298. The deviation was 0.238. When the micro wave recipient was placed in the position l of 6 cm, there was evidently some deviation between the theory-based calculation and data-based calculation. The theory-based caculation yielded 0.494554 whereas the data-based calculation arrived at 0.047892. The deviation was 0.4467

Abstract

Telah dilakukan penelitian untuk menunjukkan bahwa energi elektron suatu atom itu terkuantisasi, memahami kurva Franck-Hertz dari peristiwa penyerahan energi yang tidak kontinyu oleh elektron bebas kepada atom Mercury dan menentukan energi eksitasi atom Mercury serta menentukan panjang gelombang foton yang dipancarkan. Dalam penelitian ini telah dibuktikan bahwa energi elektron dalam atom itu terkuantisasi kenyataan ini mendukung teori atom Bohr. Kurva yang terbentuk sangat mirip dengan kurva hasil percobaan Franc-Hertz yang sebenarnya, perbedaan yang ada adalah suhu uap Mercury dalam percobaan ini hanya 1300 C sedangkan aslinya adalah 1800 C. Energi eksitasi yang diperoleh dari percobaan ini adalah 5 eV dan panjang gelombang foton yang dapat diukur dari percobaan ini adalah 2486,25 A0 .
