Question:
Which of the following is an optically active substance?
Which of the following is an optically active substance?
Show Hint
Quartz is commonly used in polarimetry due to its optical activity.
Updated On: Jan 3, 2026
- Calcite
- Tourmaline
- Quartz
- Sodium Chloride
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
An optically active substance rotates the plane of polarized light. Quartz is known for its natural optical activity, while calcite and tourmaline only exhibit birefringence.
