Analog voltmeters use a galvanometer as well as a series resistance that advances a pointer around a scale by a voltage detected. Amplifier-based metres can detect voltages as low as a few microvolts. An analog-to-digital converter is used in electronic voltmeters to show temperature numerically. Voltmeters come in a variety of forms, some of which […]

If you want to learn about the wave theory of light, Young’s Double Slit Experiment is a great place to start. This experiment was first conducted by Thomas Young in 1801, and it helped to firmly establish the wave theory of light. The basic principle behind this experiment is that light behaves as a wave

When two waves collide, they can create a variety of outcomes. In some cases, the two waves will merge and create a new wave. In other cases, the two waves will cancel each other out and produce silence and in still other cases, the two waves will interact with each other to create interference patterns.
