Types of waves through space

  1. Aug 17, 2009 #1
    I know there are different types of waves in matter, for example P waves, S waves, etc. But do these correlate to waves in space? For example I know of two types of waves through space: gravitational waves and light waves, which both travel at precisely the same speed. Are there any more types of waves through space?

    I don't know if they correlate to waves in space because I don't really understand big words such as correlate (Only 13) but for the second question there are electromagnetic waves. Unless that is what you meant by light waves. If not then you should know that light is an electromagnetic wave, and all electromagnetic waves travel the same speed (the speed of light).
