SCIENCE 10 Q1 M2
Texte du Storyboard
- Good day, class! Have you prepared the activity I provided? If yes, please present your output to the class.
- Calling Ms. Yra and Ms. Daphne to present their output first to the class.
- In 1603, William Gilbert discovered that the Earth was magnetic and theorized that electricity and magnetism are not the same
- In 1785, Charles Augustin de Coulomb developed the Coulomb's law which defined the electrostatic force of attraction and repulsion
- He used a magnetic compass. He placed that magnetic compass on a table and he noticed that whenever
- In the year 1820, Hans Christian Oersted accidentally discovered that electricity could produce magnetism while conducting an experiment in his class
- Joseph Henry first discovered electromagnetic induction in 1831 along with Michael Faraday.
- Wilhelm Eduard Weber discovered that the ratio of electrostatic to electromagnetic units equals the value of the speed of light, leading to the conjuncture that light is an EM Wave on 1856
- Heinrich Hertz proved the existence of radio waves through his experiments on 1887 and Albert Einstein formulated the concept of photoelectric effect on 1905.
- James Clerk Maxwell described how electric charges and currents act as sources of electric and magnetic fields. He then formulated four (4) equations or known as the Maxwell's Equations, which summarizes the relationship between electricity and magnetism. He described it on 1861.
- You've all done well with the activity I handed out. It was all precise and presented the timeline of scientists and their contributions in the electromagnetic wave theory of James Clerk Maxwell. Although Maxwell was the person who founded the Electromagnetic Wave Theory, the scientists stated gave huge contributions in order to propose the said theory.
- Congratulations, students! You have all passed!
