Question

mission wm1: nature and categories of waves
which one of the following best describes the means
by which a wave transports its energy along a slinky
from coil a to coil z?
a. coil a pushes on coil b which pushes on coil c
which pushes on ... coil z.
b. coil a trades positions with coil b and then with coil
c ... and finally with coil z.
c. coil a and coil z trade positions.
d. ... nonsense! waves do not transport energy along
the medium; theyre simply vibrations.

Explanation:

To determine how a wave transports energy along a slinky, we analyze each option:

• Option a: Waves transfer energy through the medium by particles (coils) exerting forces on adjacent particles. Coil A pushes Coil B, which pushes Coil C, etc., transferring energy to Coil Z. This matches wave energy transfer (particles oscillate in place, transferring energy to neighbors).
• Option b: Waves do not involve particles trading positions (they oscillate around equilibrium, not move along the medium).
• Option c: Coil A and Z trading positions is incorrect (particles don’t move across the entire slinky).
• Option d: Waves do transport energy through the medium (e.g., sound, slinky waves transfer energy), so this is false.

Answer:

a. Coil A pushes on coil B which pushes on coil C which pushes on... coil Z.
