Correct Answer: Red
Solution : The correct answer is Red.
When passing through a prism, red light deviates the least from the other colours of visible light. This phenomenon occurs because various colours of light have different wavelengths, and the angle at which light is refracted (bent) when it travels through a prism is proportional to its wavelength. Red light has a longer wavelength than other visible spectrum colours (such as blue or violet), and hence, it bends less while passing through a prism, resulting in a lower angle of deviation.
