• diffraction

• reflection

• refraction

Which statement best describes how sound transfers energy through different types of mediums?

• Sound travels fast through solids because the particles are closer together.

• Sound travels faster through space because there are no air particles to slow it down.

• Sound travels the slowest through liquids because the particles are harder to move.

• Sound travels at the same rate in any medium because the distance between the particles does not matter.

A student conducted an investigation to compare the quality of signal transmission of radio waves and microwaves through different materials. The student's data is shown in the table below. What can be concluded about the student's investigation?

• The transmission quality of radio waves is unaffected by different materials and microwaves are not able to transmit through materials.

• Radio waves and microwaves transmit well through air, plastic, and glass, but microwaves are more affected by the other materials.

• Radio waves and microwaves transmit well through air, plastic, and glass, but transmission of both types of waves is reduced by wood, brick, and concrete.

• Neither radio waves nor microwaves can effectively transmit through brick or concrete.

A student conducted an investigation into how different materials affect data signals transmitted by microwave, radio, and ultraviolet waves. Their experimental results are listed in the provided data table. What can be concluded about the student’s investigation? Select TWO correct answers.

• The materials’ impact on data transmission varies depending on the type of wave.

• The materials do not have an affect on the transmission of data by different types of waves.

• The transmission of data signals by different types of waves is affected by the material it is moving through.

• The properties of a material affects its ability to transmit data signals.

• Wave properties are changed by the type of material it moves through.

A seismic wave from an earthquake traveling through Earth's mantle reaches the boundary between the mantle and the crust. The mantle and crust are different in many ways, including their density and composition. What happens as the seismic wave passes from the mantle to the crust?

• The wave dissipates entirely when it reaches the boundary.

• The seismic wave is completely reflected and does not pass into the crust.

• The seismic wave continues traveling at the same speed, undisturbed by the transition.

• The seismic wave changes direction and speed as it enters the crust.
