Below are sample questions representative of the exercises included on this worksheet and related 9.73 Mechanical and Electromagnetic Waves skill assessments:

Problem 1Difficulty: Mastery

Use the chart. Which rule best summarizes the data?

AMechanical waves require matter, while electromagnetic waves can travel through vacuum.

BAll waves require matter because all waves carry energy.

CVisible light and radio waves are mechanical because they can be detected.

DSound and seismic waves can travel through vacuum if they are strong.

Solution & Explanation:The data separate waves by medium requirement. Sound and seismic waves need matter; visible light and radio waves can travel through vacuum.

Problem 2Difficulty: Mastery

Which statement is most precise about a medium in the context of waves?

AA medium is a detector that turns light into sound.

BA medium is matter that carries a mechanical disturbance from one location to another.

CA medium is only the air needed by visible light.

DA medium is empty space that all waves require.

Solution & Explanation:For mechanical waves, a medium is the matter through which the disturbance travels. Electromagnetic waves do not require a material medium.

Problem 3Difficulty: Mastery

A seismic wave in rock is compared with a radio wave sent from a spacecraft. Which difference most directly affects where each can travel?

AThe seismic wave is electromagnetic; the radio wave is mechanical.

BBoth waves require the same solid path.

CThe seismic wave needs a material medium; the radio wave can travel through vacuum.

DThe radio wave needs air, but the seismic wave needs no matter.

Solution & Explanation:The seismic wave is mechanical and must travel through matter such as rock. The radio wave is electromagnetic and can travel through space.
