What is the relationship between wavelength and speed?
What is the relationship between wavelength and speed? Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. What is the longest […]

Can an electric field be infinite?
Can an electric field be infinite? 3 Answers. So there is no infinity. In two dimensions (or in one), the electric field falls off only like 1r so the potential energy is infinite, and objects thrown apart get infinite speed in the analogous two-dimensional situation. Does electric field increase with distance? Electric field strength is […]
How do you calculate the voltage after a resistor?
How do you calculate the voltage after a resistor? Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor […]
