Electromagnetic waves are transverse waves, since the electric and magnetic fields oscillate at a right angle to the direction of motion. ]]> 2016-12-19 18:21:17 UTC https://padlet.com/4328232118/629du5sdp63n/wish/144364665 4328232118 https://padlet.com/4328232118/629du5sdp63n/wish/144364859 Mechanical longitudinal waves are also called compressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium.

The most common unit of frequency is the hertz.
