7.According to the particle model,which has more energy blue light or red light? Explain your reasoning. __

Blue light has more energy than red light.<br /><br />**Reasoning:**<br /><br />The particle model of light describes light as being made up of discrete packets of energy called photons. The energy of a photon is directly proportional to its frequency. Blue light has a higher frequency than red light (blue light has shorter wavelengths, and wavelength and frequency are inversely related). Therefore, since blue light has a higher frequency, its photons have higher energy than the photons of red light.<br />
