Question

Use a 1m long table to replicate the Bedford Level Experiment. Briefly mention how did you carry out the experiment to prove the shape of the earth.

Answer 1

• Setup: Place the 1-meter-long table on a flat surface, ensuring it is level. Attach three poles of equal height at the ends and middle of the table.
• Observation: From one end of the table, observe the height of the middle pole compared to the other two. If the Earth were flat, all three poles would be at the same height. However, due to the curvature of the Earth, you would notice that the middle pole appears slightly higher than the two end poles.
• Conclusion: This difference in height, just as in the original Bedford Level Experiment, proves that the Earth is not flat but curved. The curvature causes the middle pole to appear higher than the ones at the ends, supporting the theory of a spherical Earth.
