sound waves, because they travel by oscillating molecules

light waves, because they travel by oscillating electromagnetic fields
light waves, because they travel by oscillating electromagnetic fields

light waves, because they travel by oscillating molecules

Answer 1

The correct answer is:

**sound waves, because they travel by oscillating molecules.**

Sound waves are mechanical waves that require a medium (such as air, water, or solids) to propagate by causing the particles of that medium to oscillate. In contrast, light waves are electromagnetic waves that do not require a medium to travel through.
