MCQ
The splitting of white light into its constituent colours by a triangular prism is called ________?
- ADispersion
- BReflection
- CRefraction
- DScattering
✓
Answer
- Dispersion
Explanation:
The white light is separated into its component colors - red, orange, yellow, green, blue, indigo and violet.
The separation of visible light into its different colors is known as dispersion.
On passing through the prism, each colour of light ray is refracted by a different amount and hence, white light is split into its component colours.
