When white light passes through a prism, the color which deviates the most is violet (Option B). This deviation occurs because different colors of light have different wavelengths and thus bend by different amounts when passing through a medium like a prism. Violet light has the shortest wavelength among visible colors, around 380-450 nanometers. Due to its shorter wavelength, it experiences a higher refractive index in the prism material compared to colors with longer wavelengths, like red. Consequently, violet light refracts, or bends, more sharply than the other colors, resulting in the greatest deviation. This is why violet appears at one end of the spectrum when white light is dispersed by a prism, demonstrating the principle of dispersion where different wavelengths of light spread out to form a continuous spectrum.
