What is the relationship between the direction of oscillation of an electromagnet wave and it's direction of travel?

The oscillations are perpendicular to the direction of travel.  

Step-by-step explanation:

An electromagnetic wave has oscillating electric and magnetic fields.

They oscillate at right angles to each other and perpendicular to the direction of travel of the wave.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
