Light waves are electromagnetic waves and do not require a medium to propagate (they can travel through a vacuum). Light waves are transverse waves, meaning the oscillations of the electric and magnetic fields are perpendicular to the direction in which the wave travels.
Therefore, sound waves are longitudinal in air, and light waves are transverse in air (and other media, or vacuum).
– Light waves are always transverse.
