Read the passage and answer the following question(s).



Speed of Light and Sound Waves



A student investigates the speed of waves through different materials. The student knows that sound is a mechanical wave that travels on longitudinal waves, while light is an electromagnetic radiation that travels on a transverse wave. A sound and light wave are shown.

The student measures the speed of sound as it passes through three different materials. The type of material, density of the material, and speed of sound as it passes through each material are recorded in the data table.

The table shows the density of four materials.



Material Density (g/cm3)
Water
1.00

Steel 7.86
Aluminum 2.58
Polyethylene (plastic) 0.92




Through which material will sound travel the fastest?


steel


water


aluminum


polyethylene (plastic)

Answered by GPT-5 mini AI
steel

Explanation: Sound waves travel fastest in solids because particles are close together and materials are stiffer. Of the choices given, steel (a stiff solid) will transmit sound faster than water, aluminum, or polyethylene.
