What frequency means? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. What happens to pitch when frequency […]

Why do electrons move in magnetic field?
Why do electrons move in magnetic field? Cyclonic movements Free-electron Landau states are a form of quantized state adopted by electrons moving through a magnetic field. All charged particles interact with electromagnetic fields via the Lorentz force. This interaction causes electrons in a magnetic field to move in a corkscrew pattern. Are electrons attracted to […]
Is fission or fusion more dangerous?
Is fission or fusion more dangerous? In 2019, National Geographic described nuclear fusion as the “holy grail for the future of nuclear power.” Not only would it produce more energy more safely, it would also produce far less harmful radioactive waste than fission, from which weapons-grade material in spent fuel rods taking millions of years […]
