To show iPad's view on Macbook This tutorial raised a question if you can mirrow the screen of iPad Air through a cable to the newest Macbook Air. 

So I think the cable should be something


the power cable of iPad air To Lightning place of Macbook air


Does there exist any such cable by which you can show the picture of your iPad on your Macbook Air?
No, Apple provides no official way of doing this.

If you really need to, you could use Option 3 listed in the tutorial you linked to, the Apple Digital AV Adapter, combined with some sort of external video capture device for you Mac like the Elgato Game Capture HD Game Recorder.
