In this scene two of the main characters are having a battle with light sabers and the sounds that can be heard are coming from the light sabers as they are swung and hit together therefore this is diegetic sound.        In this scene there are space ships having a battle with each other and you can hear the guns firing and the noise of the ships as they fly past therefore the noise in this scene is also diegetic sound.

In this scene there is non diegetic sound as there is no sound coming from the scene itself and the non diegetic sound is one high pitched key on a piano which makes this scene a bit tense.
