PhET interactive simulations provide an extensive suite of simulations for teaching and learning Physics. PhET interactive simulations in Physics include- Sound & Waves, Work, Energy & Power, Light & Radiation, Electricity & Magnetism and others. PhET simulations are open source and hence free for all students and teachers. These simulations are very effective in concept learning. Read more
