Solution

  1. Violet is the colour that bends the most when white light travels through a glass prism because it has the shortest wavelength and is refracted the most.
  2. Red, on the other hand, is the colour that bends the least because it has the longest wavelength and experiences the least amount of refractive error. Indigo, blue, green, yellow, and orange are the other colours of the spectrum, which are indicated in order of increasing wavelength.
