These rays travelled in opposite direction of the cathode rays and passed through the holes of the cathode and struck the other end of the discharge tube. When these radiations struck the end of the tube P, the fluorescent radiations were also produced. These rays were called canal rays because they are passed through ...

Dalton's ideas proved foundational to modern atomic theory. However, one of his underlying assumptions was later shown to be incorrect. Dalton thought that atoms were the smallest units of matter − - − minus tiny, hard spheres that could not be broken down any further. This assumption persisted until experiments in physics showed that the atom was composed of even smaller particles. In this article, we will discuss some of the key experiments that led to the discovery of the electron and the nucleus. In the late 1 9 th 19^ 1 9 th 19, start superscript, start text, t, h, end text, end superscript century, physicist J.J. Thomson began experimenting with cathode ray tubes. Cathode ray tubes are sealed glass tubes from which most of the air has been evacuated. A high voltage is applied across two electrodes at one end of the tube, which causes a beam of particles to flow from the cathode (the negatively-charged electrode) to the anode (the positively-charged electrode). The tubes are called cathode ray tubes because the particle beam or "cathode ray" originates at the cathode. The ray can be detected by painting a material known as phosphors onto the far end of the tube beyond the anode. The phosphors spark, or emit light, when impacted by the cathode ray. A diagram of J.J. Thomson's cathode ray tube. The ray originates at the cathode and passes through a slit in the anode. The cathode ray is deflected away from the negatively-charged electric plate, and towards the positively...

What Are Anode Rays? When careful experiments were carried out using perforated cathode in the discharge tube, a new type of rays known as anode rays were revealed. These rays after emitted by anode pass through the pores made in the cathode surface. These rays carry a positive charge and hence also known as positive rays. These rays carry positive charged particles and their e/m ratio changes from gas to gas unlike the e/m ratio of the constituent particles of cathode rays. Actually these positively charged constituents of the anode rays are nothing but the atoms of the gas left after one or more electrons are knocked out of them. Hydrogen is the lightest element and gives smallest positive particles and is known as proton. The charge carried by a single proton/electron is the smallest charge carried by any particle. For the same reason only, the charge on one proton is called unit positive charge and on one electron is called unit negative charge Properties of ANODE Rays (i). They consist of Positively charged particles. Their mass is virtually the same as that of the atoms from which they are derived and is found to be equal to the atomic mass of the gas in the discharge tube. (ii). They travel in straight lines. (iii). They are capable of producing physical and chemical changes. (iv). They can penetrate thin metal foils. (v). They can produce ionization in gases. (vi). They are deflected by electrical and magnetic fields just as the cathode rays but in opposite directi...
