Question

Geodimeter is based on:

• A. Propagation of modulated light waves
• B. High frequency radio waves
• C. Intermittent signal of high frequency near 500 MHz
• D. Propagation of infrared radiation

Hint:

Geodimeters use modulated light waves for precise distance measurement, especially in surveying.

Answer 1

The Correct Option is A

A geodimeter measures distances based on the propagation of modulated light waves. These waves are sent to a target and reflected back, allowing the instrument to calculate distance by measuring the phase difference or travel time of the light.
