Light Intensity vs Power for a Small Incandescent Lamp

WebIntro to Interference of Light. One of the consequences of the wave nature of light is that the principle of superposition applies: two waves can be combined by simply adding their amplitudes. If both waves are at their maximum amplitude A, then the result is 2A. If they are both at the minimum amplitude, − A, then the result will be − 2A. WebWien's Displacement Law. For a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV.
