Physics · Light - Dispersion and Refraction
During the dispersion of white light by a glass prism, the more a colour component bends, the higher is the refractive index of the glass for that colour. If μ B , μ Y , and μ G are the refractive indices of glass for blue, yellow, and green lights respectively, which of the following relations is correct?
- 1μ Y > μ G > μ B
- 2μ Y = μ G = μ B
- 3μ G > μ B > μ Y
- 4μ B > μ G > μ Y✓
Correct answer
μ B > μ G > μ Y
