When white light passes through a PRISM, it splits into seven colours. This phenomenon is called:
AReflection, with light bouncing back
BRefraction, simply bending of all light
CDispersion of white light into spectrum
DDiffraction around fine narrow obstacles
Answer & Solution
Correct answer: C. Dispersion of white light into spectrum
Dispersion is the splitting of white light into its seven constituent colours (VIBGYOR) by a prism. Newton (1666) showed white light is a mix of colours. Different colours bend by different amounts; violet bends most, red bends least.
