How does the color of light affect its energy level?

The energy of light is directly related to its wavelength, with shorter wavelengths corresponding to higher energy. Light can be thought of as electromagnetic radiation, where different colors represent different wavelengths within the visible spectrum. Red light has the longest wavelength and the lowest energy among visible light colors, while blue light has a shorter wavelength and therefore higher energy.

When examining the electromagnetic spectrum, you can see that as you progress from red (with longer wavelengths) to blue and then to violet (with the shortest wavelengths), the energy associated with the photons increases. Thus, blue light indeed carries more energy than red light. This understanding is crucial in areas such as photonics and explains phenomena like the increased energy of blue light in applications such as lasers and LEDs.
