Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
• The question asks which method is used to measure length.
Step 2: Detailed Explanation:
• The RADAR method uses the time taken by a radio wave to travel to an object and back to measure large distances (length).
• Dimensional, pendulum and angular methods are not methods of measuring length directly.
Step 3: Final Answer:
The correct option is (D) RADAR method.
• The question asks which method is used to measure length.
