Question

which of the following is true about sound waves and light waves?
a. all sound waves and light waves are longitudinal waves
b. most sound waves are longitudinal waves, while light waves are transverse waves
c. all sound waves and light waves are transverse waves
d. most sound waves are transverse waves, while light waves are longitudinal waves

Explanation:

Sound waves (mechanical waves that propagate through media like air, water) are almost always longitudinal, meaning particle motion is parallel to wave direction. Light waves are electromagnetic transverse waves, where oscillation is perpendicular to wave direction. This eliminates options A, C, D which misstate these wave types.

Answer:

B. Most sound waves are longitudinal waves, while light waves are transverse waves.
