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

Answer: (c). Light (electromagnetic) travels in vacuum; sound (mechanical) does not, so (a) is false. Sound in air is longitudinal; light is transverse. So the answer is (c).
