Answer :
To determine which statement is best supported by the observations recorded in Levi's chart, let's analyze the behavior of the waves provided.
1. Wave W: It travels fastest through metal. This is a characteristic of sound waves, as they travel faster in solids due to the densely packed molecules that allow quicker transmission.
2. Wave X: It travels fastest through air. This characteristic suggests it might be a light wave because light travels faster in air than any medium with a higher density. Sound also travels through air, but since no other medium (such as a solid or liquid) is mentioned for this wave, it isn't as strongly supported as a light wave by only this observation.
3. Wave Y: It travels more slowly through water than through air. This characteristic aligns with sound waves because sound waves generally travel faster in air than in water.
Based on these observations, let's align them with the provided statements:
- Wave W and Y are light waves: Incorrect. Wave W appears to be a sound wave, and Wave Y likely a sound wave.
- Wave X is a sound wave: Incorrect. There's no mention of comparing mediums for sound propagation.
- Wave W is a light wave: Incorrect. Wave W is likely a sound wave.
- Waves X and Y are sound waves: Partial, But less likely. Wave X has no sufficient evidence for being a sound wave.
- Wave Y is a sound wave: Correct. Wave Y's slower speed in water than air aligns well with sound wave characteristics.
- Waves X and W are light waves: Incorrect. Wave W is not indicated as a light wave.
- Wave W is a sound wave: Correct. This matches the observation of fastest travel through metal.
- Waves X and Y are light waves: Incorrect. Wave Y is indicated more strongly as a sound wave.
The best-supported statements, therefore, are:
- Wave Y is a sound wave.
- Wave W is a sound wave.
From these two correct options, the most well-supported singular conclusion would be:
Wave W is a sound wave.
