Concept:Sound waves in air are longitudinal; light waves in air are transverse.
Explanation:Sound waves cause air particles to vibrate parallel to the direction of wave travel.
This creates compressions and rarefactions along the same line.
Thus, sound is a longitudinal wave in air.
Light waves consist of oscillating electric and magnetic fields.
These fields oscillate perpendicular to the direction of wave propagation.
Therefore, light is a transverse wave in air.
Hence, sound is longitudinal and light is transverse when traveling through air.
Answer:Option (1): respectively longitudinal and transverse in air.
