Question

one type, called longitudinal waves are a
. these waves travel in the same direction that
. sound is an example of this wave
light.
. unlike sound, light is a
. it can move through empty space.
choose the correct answer.
which type of wave is light?
longitudinal
mechanical
transverse

Explanation:

Light is an electromagnetic wave. Electromagnetic waves are transverse waves. Transverse waves have oscillations perpendicular to the direction of wave propagation. Longitudinal waves (like sound) have oscillations parallel to the direction of wave propagation. Mechanical waves require a medium (e.g., sound needs air, water, etc.), but light (an electromagnetic wave) can travel through a vacuum (no medium). So light is a transverse wave.

Answer:

Transverse
