A row of identical beads is connected by light springs. The position of each bead is measured from the left-hand end of the row.
A student moves bead 1 backwards and forwards briefly. Sensors record data for three of the beads.
| bead | position before movement in m | minimum position during movement in m | maximum position during movement in m | position after all movement stops in m | time at which bead starts moving in s |
|---|---|---|---|---|---|
| 1 | 0.050 | 0.045 | 0.055 | 0.050 | 0.00 |
| 10 | 0.500 | 0.495 | 0.505 | 0.500 | 0.36 |
| 20 | 1.000 | 0.995 | 1.005 | 1.000 | 0.76 |
The student claims that bead 1 carries the energy along the row to bead 20.
Explain whether the data support the student's claim.
