Light is not a mechanical wave. So no need to have a material medium to pass through. Even through vacuum light can travel. Because it is an electromagnetic wave. As electrical and magnetic disturbance pass on in the form of transverse wave the distance between successive crests is defined as the wavlength of the wave. Here crest means the field intensity becoming maximum.
