Which one of the following statements is true? (a) The sound waves in air are longitudinal while the light waves in air are transverse. (b) Both light and sound waves in air are transverse. (c) Both light and sound waves in air are longitudinal. (d) The sound waves are transverse and light waves are longitudinal.

Answer: (a). Sound in air travels as compressions and rarefactions, so particles vibrate along the direction of travel: longitudinal. Light is an electromagnetic wave with E and B perpendicular to the direction of travel: transverse. So the answer is (a).
