QUANTUM PHYSICS PART 4: WAVE-PARTICLE DUALITY + DE-BROGLIE WAVELENGTH + HEISENBERG UNCERTAINTY
Prior to quantum mechanics, there was a long standing battle between physicists whether light consists of particles or whether they are waves. Newton believed strongly that they are particles and the Dutchman Huygens believed that they were waves. And it seems like in 1980, a conclusive experiment done by Young who demonstrated unambiguously that light was waves. Huygen was right. But soon, there were also experiments that showed rather conclusively that light is made up of particles. It was one of the greatest victories of quantum mechanics that it showed that light is both. At times, it behaves like waves and at other times, it behaves like particles. It all depends on how you do the experiment.
We explored the final installment of Quantum Physics, Wave Particle Duality as shown by de Broglie's equation, and moved on to look at the strange world of Heisenberg's Uncertainty Principle. Of course, we understood that these strange phenomena are only observable in the sub-atomic world, not in our macro world. :)
THE PHYSICS CAFE is founded by renowned physics tutor and ex-RJC lecturer Mr Dave Sim in 2010. It is a tried and tested specialist’s tuition centres for Secondary/IP and JC Physics, Maths and Chemistry. As one of the most reviewed tuition centres by parents and students, it is also featured in The Straits Times, The New paper, asiaone.com, Vulcan Post and many other news outlets. The locations are conveniently located next to Beauty World MRT, Novena MRT and Paya Lebar MRT and Bishan MRT.
They have a team of highly sought-after tutors who are chauffeured by the school driver between the centre to ensure consistent high standard of our lessons. The stellar academic results produced by the students and the number of students we attracted prove that this is a winning formula. 80% of the students consistently scored “A” in their GCE A-level examination and 90% of the IP/Sec students consistently scored “A” in their final IP Exam and GCE O-level examination This doubles the steady national average of 40 percent A and is higher than the percentage A of the top IP schools in Singapore.
“The course structure in PMC is built based on my belief that we should spend time to develop the student’s problem-solving skills, instead of concepts. Once you are good in problem solving, you will be good in concepts. Once you are good in the subject, you will love it. LOVE will always come the last.”
