Sound waves are electromagnetic waves
Questions & Step-by-Step Solutions
Which of the following statements about sound waves is true?
Step 1: Understand what sound waves are. Sound waves are vibrations that travel through a medium, like air, water, or solids.
Step 2: Learn about wave types. Waves can be classified as longitudinal or transverse. Longitudinal waves have particle movement in the same direction as the wave travels.
Step 3: Identify the type of sound waves. Sound waves are classified as longitudinal waves because the particles of the medium move back and forth in the same direction as the sound wave travels.
Step 4: Confirm the statement. Since sound waves are longitudinal, the statement that 'sound waves are longitudinal waves, meaning the particle displacement is parallel to the direction of wave propagation' is true.
