The cathode ray tube had applications in production of luminescence on a screen which was chemically affected on which the cathode rays were allowed to pass through the narrow aperture by focusing on the dot look alike beam. The introduction of Karl Ferdinand Braun’s oscilloscope ended the race of the search of all the researchers in the year 1897. Many researchers were thrilled to get to know the secret behind the cathode rays, while many where actually in search of the applications of the cathode ray tube experiment. NCERT notes Class 11 Chemistry Chapter 2 Structure of AtomĪpplications of the cathode ray tube experimentĭuring the time unknown, the cathode ray tubes has applications in the electron beam in which there was no consideration of inactivity but have high level of frequencies and for a small fraction of time it can be made visible.

By noting the places carefully where the fluorescence is observed, it was pointed out that the positive side was the sight where the deflections where noted. This confirmation was further done by placing a substance which is phosphorescent in nature towards the end of the discharged ray.The ray is repelled by the negative pole and is deflected back to the positive pole, as the dipoles are applied.On either side of the discharge ray a negative and positive pole is retained.A dipole is set up in experiment in addition to recognize the components of the ray given out by applying the tube a high voltage.As the circuit is complete, the electricity starts flowing.The metal pieces are supplied with a high voltage for air ionization to make it a good conductor of electricity.The set is made is such a way to give source of high voltage and draining the air to maintain low pressure inside of the tube.The air is completely drain out of the glass tube to keep the pressure of gas low.

There is external voltage in connection with the two metal pieces. The set- up of the apparatus is done is manner such that there is in co-operation of a glass tube comprising of two metal pieces towards the opposite end which behaves as electrodes. The cathode rays consist of electrons which are negatively charged in nature. The single ray of electrons can be transformed in a manner to show pictures in natural colours which are in movable motion.

The image cast back electrical waves forms photographs, radar detected aircraft echoes and much more. The beam of electrons is diverted in such a way that permit an image appearing on the projector.

The German physicist Karl Ferdinand Braun, is the inventor of cathode ray tube in such a way that the cathode rays have an evacuated glass envelope comprising of an electron gun as a source of electrons and a light which is fluorescent with means of acceleration present internally or externally to divert the electrons. The cathode ray is built in such a way that all the air has been drained out of the tube. The discovery of electron led by sir J.J Thomson through cathode ray tube experiment is one of the most well received experiment in physics. A small fraction of energy is changed into X-rays. When the electrons reach towards the end, all the energy left in them id given up by the electrons because of their speed and that is transformed into other energy namely, heat. In the cathode ray tube, electrons are transferred from one side of the tube towards the other end by means of electrical field.
