Why are heat waves transversal?

If you mean heat say from the Sun, Maxwell's equations have E and B fields that are transverse to the propagation direction. If you mean “waves of heated gas”, the are not transverse, they are essentially longitudinal density waves. read more

Gamma rays are longitudinal.All electromagnetic waves are transverse in nature that is their vibrations are perpendicular to the direction of travel of waves. read more

Infrared waves are also called thermal radiations or thermal waves . As in nature most of the heat is transferred from one body to the other body in the form of infrared waves . Therefore, you can say heat is transferred by means of transverse waves . All electromagnetic waves are transverse in nature according to Maxwell. read more
