You will remember from section I that normal T waves tend to be slightly asymmetrical in shape and less than 50% of the height of the proceeding all waves.

Light doesn't need a medium to travel through, it can travel through the vacuum of space, but it still follows the same principles as all waves namely reflection, refraction and diffraction.
