Final answer:
Blue light bends more than red light when passing through a prism due to its shorter wavelength, demonstrating the principle of dispersion.
Step-by-step explanation:
When red and blue light pass through a prism, the color that bends more is blue light. This occurs due to a phenomenon known as dispersion, where light separates into various colors with different wavelengths when it passes through a material like glass or water. We understand that light bends toward the normal upon entering a material with a higher index of refraction, and this bending varies depending on the wavelength of the light. Shorter wavelengths of light, such as blue and violet, are bent more than longer wavelengths like red. Hence, if we specifically compare red and blue light, blue light with its shorter wavelength is bent more than red light when refracted through a prism.
