Investigating attenuation in optical fibres

Plan Aim My aim is to investigate the f strikeors which act the attenuation of invisible emission ray of light of light in an optical fibre modelled by plain gel. I pass on larn how the length and width of the gelatin affect how the actinotherapy is attenuated. The passing of the frenzy of the infrared radiation is represent by the sum up of potential drop crosswise the infrared demodulator. If the intensity of the radiation is high, therefore the voltage across the infrared sensing element will also be high. Apparatus (before polisher investigates) Infrared transmitter and sensing element Ruler / vernier exceed callipers Knife Multimeter ( Wires x 2 Bunsen burner Plastic container Tripod and gauze Glass rod Clear gelatine gunpowder 2 x 250cm3 beakers Matches Power pack Pilot experiments I carried out a consecutive publication of pilot experiments in order to determine the simulacrum of lengths and widths that I will be investigating. I also require to make up ones psyche the correct proportions of the gelatine powder and water to use for the gelatin to be firm and consistent. Modifications do during pilot experiments I found that give 400cm3 of water and 1 sachet of gelatine left the jelly to bland to be apply in the experiment. I therefore apply 500ml of water and 2 ½ sachets of gelatine (44.25g).

I found that there was a potential difference across the infrared detector plunder when the infrared emitter was switched off. The IR radiation being picked up is from the energetic environment of the detector. Whilst carrying out my experiment it would pose a massive problem to allow any background radiation to consult the IR detector. When I vary the dimensions of the jelly, I could obtain ill-advised results. For example, if the length of the jelly were shortened, the voltage across the infrared detector should increase to a accredited value. However, if there...
