To determine the best-supported statement by the observations in Hans’s chart, let's analyze each wave's behavior one by one:
1. Wave W:
- Observation: Scatters through a small opening to form a ray of light.
- This behavior is characteristic of diffraction, where a wave bends around the edges of an obstacle or opening.
2. Wave X:
- Observation: Bounces off a mirror.
- This behavior is characteristic of reflection, where a wave changes direction at a boundary between two different mediums, remaining in the original medium.
3. Wave Y:
- Observation: Changes colors as it passes through a crystal.
- This behavior is characteristic of refraction, where a wave changes speed and direction as it passes through different materials, resulting in phenomena such as dispersion, which can change colors.
4. Wave Z:
- Observation: Bends as it passes through an object.
- This behavior is also characteristic of refraction, where a wave bends due to a change in speed when passing from one medium to another.
Based on these analyses:
- Wave W is being diffracted.
- Wave X is being reflected.
- Waves Y and Z are being refracted.
Therefore, the statement that is best supported by the table is:
"Wave W is being diffracted, Wave X is being reflected, and waves Y and Z are being refracted."
Thus, the correct statement is:
Wave [tex]$W$[/tex] is being diffracted, Wave [tex]$X$[/tex] is being reflected, and waves [tex]$Y$[/tex] and [tex]$Z$[/tex] are being refracted.
