alleryLight with no preferred direction of vibration is:
ARefracted
BDiffracted
CUnpolarised
DPolarised
Answer & Solution
Correct answer: C. Unpolarised
1. Light waves vibrate across the direction of travel.
2. In ordinary light those vibrations lie in all such directions.
3. That light is called unpolarised.
