As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:

E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.

Therefore, the answer is B) different amounts of energy in white light.
