Question

A soundwave is transmitted through four unknown materials. The densities of each material are included in the table below. In a few sentences, explain which material the soundwave will travel fastest through and why?

To receive full credit for this item, your response must:
Choose the correct material from the options below (Either A,B,C, or D.) (1pt.)

Briefly explain why the soundwave will travel the fastest through that material. (1pt.)

Answer 1

Based on the density of the materials provided, it can be inferred that the soundwave will travel fastest through Material A. This is because soundwaves travel faster through materials with lower densities, as the particles in less dense materials are more spread out and can vibrate more freely, allowing the soundwave to travel more quickly. Therefore, since Material A has the lowest density of the four options, the soundwave will travel fastest through it.
