QQuestion
In the case of refraction of white light through a prism, the light of colour which deviates the least is
- yellow
- orange
- red
- violet
✓Answer
c. red
Explanation:
Deviation depends on the refractive index of the medium for different wavelengths.
- Violet light has the shortest wavelength, hence it bends the most (maximum deviation).
- Red light has the longest wavelength, hence it bends the least (minimum deviation).
