Question

What are the methods of judging distance? Explain any one.

Hint:

Use “Unit of Measure” for precise ranges and “Appearance Method” for quick estimates.

Answer 1

Correct Answer: Judging distance methods include:

• Unit of Measure: Use known units such as lengths of objects to estimate distance.
• Appearance Method: Estimate by comparing the appearance of objects at different ranges.
• Bracketing Method: Guess an upper and lower limit and take the average.

Explanation of “Appearance Method”: Objects appear smaller as the distance increases. For example, trees and humans are harder to identify at long ranges.
