Question

Levi observed properties of three different waves and recorded observations about each one in his chart.



Which statement is best supported by the table?

Wave W and Y are light waves.
Wave X is a sound wave.
Wave W is a light wave.
Waves X and Y are sound waves.
Waves Y is a sound wave.
Waves X and W are light waves.
Wave W is a sound wave.
Waves X and Y are light waves.

Answer 1

I don’t have Levi’s chart, so I can’t pick the single best statement yet. Could you either paste the table or tell me the observations Levi recorded for waves W, X, and Y?

If you want to decide on your own, here are quick rules that distinguish light from sound waves and let you choose the best statement from the list:

- Travels through a vacuum / extremely high speed (~3×10^8 m/s) → light wave (electromagnetic).
- Can be polarized → light wave (sound cannot be polarized).
- Requires a material medium (air, water, solid) to travel, much slower speed (~343 m/s in air) → sound wave (mechanical, longitudinal).
- Frequency in the audible range (≈20–20,000 Hz) or described as pitch → sound.
- Wavelength very short (hundreds of nm) and described as color → light.

Give me the recorded properties for W, X, and Y and I’ll pick which statement the table best supports.
