Line Spectrum example essay topic

That means, any electron of the size of 10-8 will reduce to 10-15 which is the size of nucleus as time goes with the loss of entire energy. But normally it doesn't occur. If that is the case, i.e. if electron looses its energy and diminishes in to the size of nucleus, then any object which is build by electron inn this world will start reducing. Say for example if this duster, starts reducing, then tomorrow we will see that it's having a microscopic size. This is not practical. This is true for any element in this world.

Hence no element in this earth can diminish its size drastically by itself. Now we have discussed earlier, that if we compare the size of atom to earth, then the size of nucleus would be of the size of Football. So we find that there is a huge difference and in that case, macroscopic elements will become microscopic one if electron starts diminishing and ultimately collapses on the nucleus. Hence Clark Maxwell's theory was right from its own perspective, but the assumption that Rutherford had regarding the orbit of the electron was not right. Whatever assumption, Rutherford had made was not supported by experiments. The only thing that was known from the experiment was electron was not located within the nucleus but the location was electron was not known from the experiment.

No information was available about whether electron is stationery or it moves in a orbit. But Rutherford's model gave the idea about the nucleus, about the size of the nucleus. These are the positive sides of the model, but the calculation about electron using this model was completely wrong and this is the major drawback of the model. Not only this, our initial curiosity was about the explanation of the Hydrogen Spectrum. Whenever the Hydrogen Spectrum was analyzed, there it was found a number of lines. Lot of Scientists tried to explain this Line Spectrum.

But Rutherford couldn't able to explain any of the features of the Line Spectrum. If you look at the Hydrogen Spectrum, you will find lots of lines are there within the spectrum. Diagram 3 Why there are so many lines, whether the intensity would increase or decrease, none of the points was explained by Rutherford. If we debate on the Rutherford's model, we will find that there are two major defects in his model. One is that there was no conclusion about the electron and second there was no explanation about the Hydrogen Spectrum. Spectrum.

Any element in this world is heated considerably then it will initially either absorb radiation or energy. But after some time the radiation will come out of the element. If this radiation is passed through a prism, we will find that dispersion of light happens and several times deviation also happens. If the emerging light is passed through a prism, (voice is not clear) it is the combination of monochromatic light. If it is collected on a photographic plate then we will find several lines.

This colourful array of lines is called the spectrum. But this experiment can't let you know the source of spectrum. If we heat this chalk and the radiation is passed through the prism and allowed the emerging light to fall on a photographic plate, then the spectrum which will appear, we call it as the spectrum of the Chalk. Similarly if we heat a Iron Plate, then the spectrum arising out of it, we will call it as the spectrum of the plate. Similarly if we take Hydrogen gas in a discharge tube and heat strongly. For this we (voice not clear), cover the outer portion of the discharge tube in Black cover.

Make a small hole on the discharge tube so that the radiation coming out of the tube is streamline. To make the radiation further more streamline, put a slit in between the discharge tube and the prism. The streamlined ray will fall on the prism and there dispersion and deviation will happen and finally the emerging light will fall on the plate and several lines will appear on the plate. These lines are the spectrum of Hydrogen gas.
