Which of the following pairs of light rays show the widest separation in the spectrum of white light
Answer Details
When white light is passed through a prism, it gets dispersed and is split into its constituent colors, creating a spectrum. The colors are arranged in a specific order, with red having the longest wavelength and violet having the shortest wavelength. The amount of separation between any two colors in the spectrum depends on the difference in their wavelengths. So, the pair of light rays that show the widest separation in the spectrum of white light would be those that have the largest difference in their wavelengths. Looking at the options given, we can see that the pair with the largest difference in wavelengths is blue and red, as blue has a shorter wavelength than green, while red has a longer wavelength than orange. Therefore, the answer is blue and red.
