Q: The splitting up of white light into seven components as it enters a glass prism is called:
  • A. dispersion of light
  • B. reflection of light
  • C. scattering of light
  • D. refraction of light
Correct Answer: Option A - The splitting up of white light into seven components as it enters a glass prism is called dispersion of light. The order of obtained spectrum of light is VIBGYOR. In such spectrum the red colour light has the lowest frequency and longest wavelength and vice-versa for violet.
