Question

sort each of the descriptors based on whether it applies to transverse waves only, longitudinal waves only, or both wave types.
created by a disturbance
have speed
medium motion is parallel
medium motion is perpendicular
vibrating strings
have regions of high and low densities
transverse waves only
both wave types
longitudinal waves only

Explanation:

• Transverse Waves Only:
• Medium motion is perpendicular: In transverse waves, the medium oscillates perpendicular to the wave's direction (e.g., electromagnetic waves, vibrating strings).
• Vibrating strings: A classic example of transverse waves (string moves up - down, wave moves along string).
• Both Wave Types:
• Created by a disturbance: All waves (transverse and longitudinal) start with a disturbance (e.g., plucking a string or compressing a spring).
• Have speed: Both transverse (e.g., light, wave on string) and longitudinal (e.g., sound) waves propagate with a speed.
• Longitudinal Waves Only:
• Medium motion is parallel: In longitudinal waves, the medium oscillates parallel to the wave's direction (e.g., sound waves, slinky compression).
• Have regions of high and low densities: Longitudinal waves have compressions (high density) and rarefactions (low density), like sound waves in air.

Answer:

• Transverse Waves Only: medium motion is perpendicular, vibrating strings
• Both Wave Types: created by a disturbance, have speed
• Longitudinal Waves Only: medium motion is parallel, have regions of high and low densities
