- The most.
- The least while passing through a glass prism.

उत्तर
- 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.
- 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.

State the cause of dispersion of white light passing through a glass prism. How did Newton show that white light of sun contains seven colours using two identical glass prisms. Draw a ray diagram to show the path of light when two identical glass prisms are arranged together in inverted position with respect to each other and a narrow beam of white light is allowed to fall obliquely on one of the focus of the first prism.
