Answer 2

nv > nb > nr is the correct order of refractive indices of violet, blue and red light respectively. (Option 2)

• Red is the least refracted color, violet refracts the most followed by blue.
• Refraction causes light's path to bend and change directions.
• It is because of the high rate of refraction of violet color, that the sky appears blue.
• The Angle of incidence and angle of reflection is used in measuring refraction's effect on the path of light.
• The approximate values of refractive indices of these colors are -          Red - 1.509                                                                                                    Blue - 1.516                                                                                                    Violet - 1.521
