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 student then measures the speed of light through the same materials and records the data in the table.

The student investigates the speed of sound through wood. The density of wood is 0.90 g/cm3. What observation will the student make?


Sound travels faster through wood than through water or glass.


Sound travels slower through wood than through water or glass.


Sound travels faster through wood than through water but travels slower through glass.


Sound travels slower through wood than through water but travels faster through glass.

Sound travels slower through wood than through water or glass.

Reason: Wood's density (0.90 g/cm³) is lower than water and glass, and the measured data show speed of sound increases with material density, so wood will have a lower sound speed than water or glass.
