Answer:
Red color has the lowest index of refraction
Step-by-step explanation:
In the spectrum of visible light we can observe that red is at the top and violet is at the bottom. Since v = λ . f , where is the wave velocity, is the frequency and is the wavelength of the wave so we can say that red is less deviated than violet. Therefore red has the lowest refractive index among the colors in “VIBGYOR Pattern”.
