Understanding Light Scattering in a Prism
When white light passes through a prism, it separates into its constituent colors due to a phenomenon called dispersion. This occurs because different colors of light travel at different speeds when they pass through a medium like glass.
Color Wavelengths and Dispersion
- Each color of light has a different wavelength.
- Violet has the shortest wavelength (around 380 nm), while green has a medium wavelength (around 520 nm).
- The order of colors from shortest to longest wavelength is: Violet, Indigo, Blue, Green, Yellow, Orange, and Red.
Scattering and Index of Refraction
- The index of refraction of a medium determines how much light bends when passing through it.
- Shorter wavelengths (like violet) bend more than longer wavelengths (like red).
- As light enters the prism, shorter wavelengths (violet, indigo, blue) scatter more than the longer wavelengths (green, yellow, red).
Conclusion: Why Green Scatters Less
- Among the options given:
- Violet scatters the most due to its short wavelength.
- Indigo and Blue also have short wavelengths but scatter less than violet.
- Green, having a longer wavelength, scatters the least of the four options.
Therefore, the correct answer is that while violet does scatter the most, green does not scatter much at all, making it the least scattered color from the options provided.
