Lab 5 - Essay Example However, when the value of frequency was upped to 100, as in image 5, the amplitude of spectrum obtained was more distantly spaced when compared to those previous images with frequencies 5 and 50. Overall, the experiment proves differences/ changes in wavelength when frequencies are altered. In addition, the experiment Fourier offers better insight regarding waves. The images highlighted above are those of frequency wavelength cycles of 20.5, 60 and 100 that are found in the direction of X. Proportional to the frequency value/ strength applied the 2 dots found on the right portion of the images are variously spaced. This is seen the three images 7, 8 and 9 where images 8 and 9 which have superior frequencies exhibit greater spacing between the two dots that image 7 that has frequency 20.5. Image 9 has the greatest spacing therefore, as is clearly seen. This test demonstrates that waves are not found in the direction of Y but are situated along the X direction. The images shown have two spikes divided by the Fourier transform and the image and are exhibited as two different frequencies. As observed in image 10, there exist spikes frequencies which are low at 5.5. In image 11, spikes are of high frequency, at 30.5 with two waves above 0. The first of these waves above 0 is parallel to the low waves of frequency at 5.5 and the second one also parallel but to the waves of frequencies that are high at 30.5. Moreover, the spikes on the positive section resemble mirror images of those on the negative part as observed in the images 11, 13, 15. Image 13 and 12 additionally depict the same outcome as above when their values of N1 is 5.5 and that of N2 is 70.5. This implies simply that more brightness is obtained with increase in frequency. Contrarily, image 14 and image 15 with N1 being 20 and N2 at 22 do not result in frequencies that are good as the waves move and stop repeatedly (as observable in the images). To counteract this
