WebWhen sunlight hits the cells, they emit electrons. The cells are designed so that these electrons moving around generate a voltage, and voltage can power devices. Now we can see why the photoelectric effect is such a big deal. Not only did it revolutionize our understanding of physics, but it and similar effects are used in tons of technology. WebPhotoelectric effect is regarded as one difficult topic in physics for science students because it is the abstract and multidimensional phenomenon. This study aims to develop the learning unit incorporated simulation and game with the 5E learning cycle for promoting the grade 12 science students' understanding of photoelectric effect and learning attitudes.

WebAlthough a photon is massless, it still has momentum. Einstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a ...
