Question

distinguishing sound and electromagnetic waves
sort the facts into the category that they best describe
do not require a medium to travel, transverse waves, longitudinal waves, require a medium to travel through, waves from a speaker, gamma rays
sound waves, electromagnetic waves

Explanation:

To solve this, we recall the properties of sound and electromagnetic waves:

• Sound Waves: Are longitudinal waves (particles oscillate parallel to wave direction), require a medium (like air, water) to travel, and waves from a speaker are sound waves.
• Electromagnetic Waves: Are transverse waves (oscillations perpendicular to wave direction), do not need a medium (can travel in vacuum), and gamma rays are a type of electromagnetic wave.

Sound Waves:

• longitudinal waves (sound is longitudinal)
• require a medium to travel through (sound needs matter to propagate)
• waves from a speaker (speakers produce sound waves)

Electromagnetic Waves:

• do not require a medium to travel (e.g., light, gamma rays travel in space)
• transverse waves (EM waves have perpendicular oscillations)
• gamma rays (gamma rays are electromagnetic radiation)

Answer:

Sound Waves:

• longitudinal waves
• require a medium to travel through
• waves from a speaker

Electromagnetic Waves:

• do not require a medium to travel
• transverse waves
• gamma rays
