ScanSolve AI Answer

Here are the answers to the questions based on the diagram:

  1. The experiment demonstrates that light travels in a straight line.

  2. When cardboards A, B, and C are in a straight line, the eye will see the light from the lamp.

  3. When cardboard B is shifted, the eye will not see the light from the lamp. This is because the hole in cardboard B will no longer be aligned with the holes in A and C, blocking the straight path of light from the lamp to the eye.
