⚔️🔬 Science 🔬⚔️ The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred, Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us ...
💫PHOTOELECTRIC EFFECTS 💫 * Photoelectric Effect Definition ÷ The phenomenon of emission of electrons by certain substance , when it is exposed to radiations of suitable frequency is called as " Photoelectric effect " " Photoelectric effect was discovered by Heinrich Rudolf Hertz in 1887" . * Experimental study of Photoelectric Effect ÷ Aim : To verify the phenomenon of photoelectric effects. Photoelectric effect apparatus : Evacuated glass tube having Quartz window, photo sensitive plate, metal plate, voltmeter, microammeter, commutator, battery. Photoelectric effect experimental setup {arrangement }: Observation : the Hertz experimental arrangement of photoelectric effect is shown in over above. Setup the apparatus complete the circuit as similar to the diagram .It consists of an evacuated tube having photosensitive plate 'C' and another metal plate 'A' .Monochromatic light from the source 'S...
