3.2.3. Reflecting prisms

Try these first

1. 1.

   What is the primary function of a reflecting prism in EDM?

   Hint

   Think about the role of reflectors.

2. 2.

   Why is alignment important when using a prism?

   Hint

   Consider what happens if the prism is misaligned.

3. 3.

   What is the primary role of a reflecting prism in EDM?

   • To emit EM waves
   • To reflect EM waves
   • To absorb EM waves

   Hint

   Think about what a reflector does.

4. 4.

   True or False: The size of the prism has no effect on measurement accuracy.

   • True
   • False

   Hint

   Recall the relationship between size and reflection.

5. 5.

   Discuss the implications of using low-quality prisms in a large-scale construction project. Include potential measurement errors and their consequences.

   Hint

   Think about how incorrect measurements can impact construction.

6. 6.

   Design a small experiment to compare the accuracy of different prism diameters in measuring distances using EDM. What factors would you control?

   Hint

   Consider what variables need to be the same for a fair comparison.
