(b) Find the emf of the battery. what is a quantum of electromagnetic energy? A remote control uses light waves just beyond the visible spectrum of lightinfrared light wavesto change channels on your TV. However, since each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture more of the sun's energy. More simply, this range of wavelengths is called visible light. A narrow range of wavelengths describes a: Band. each photon can be represented as a ____ __ _____ consisting of varying electric and magnetic fields that travel at the ____ __ ____.
