Correct Answer: Violet light
Solution : The correct option is Violet light .
Violet light, with the shortest wavelength in the visible spectrum, traverses glass at a slower velocity compared to other lights. The speed of light in a substance, like glass, depends on the wavelength, or colour. In glass, shorter wavelengths (violet and blue) move more slowly than longer ones (red, yellow, and green), a phenomenon known as dispersion. Dispersion in a prism leads to the separation of white light into its constituent colours due to varying refractive indices, producing a rainbow effect.
