Intensity to power

WebJul 6, 2015 · Speed is determined by whether light passes through a vacuum or some material. That leaves only amplitude as the variable available for intensity independent of the type of light and/or the medium that the light is passing through. The more photons emitted per unit time, the greater the intensity of the light. A single photon has wavelength … WebDecibel is a logarithmic unit used to describe ratios of physical values like - like power, sound pressure, voltage, intensity and more.
