When comparing the energies of red light and blue light, we need to consider their wavelengths and frequencies. Red light has a longer wavelength than blue light, which means red light has a lower frequency and therefore lower energy compared to blue light. This is because the energy of a photon is directly proportional to its frequency. Since energy (E) is equal to Planck's constant (h) multiplied by frequency (f), we can see that the energy of a photon increases with its frequency. In the case of red and blue light, blue light has a higher frequency due to its shorter wavelength, resulting in blue light photons having higher energy compared to red light photons. So, blue light has higher energy than red light due to its higher frequency.
