A wave, as I understand, is a disturbance created which causes a change in its surroundings. A longitudinal wave fits this well, is it causes compressions and rerefactions in the medium it is travelling in. These oscillating particles hit other particles and cause them to move and so on. How does a electromagnetic wave work then? Considering it does not always need a medium?

This is an interesting question. This below link provides a very good explanation. You might not understand a lot of terms used in the video, but the video is still quite good at explaining electromagnetic waves.

Also, wait till the end to see practical application of electromagnetic waves.
