why aluminium is used to jam radars?
Actually the foil is taking the place of parchment and the tuna is steamingCooking in parchment is an old french method known as en Papillote If you are cooking other ingredients with the tuna in the foil pouch, the pouch allows the flavors to meld and flavor the tunaYou could use the glass bowl and a lid, but the flavors won't be as concentrated and the tuna might dry outCooking time would probably be about the sameYou don't mention the oven temperature, so it is hard to tell.
yes you can but it might take a bit longer so check the steak at 30 and go from there
As many others above me have correctly pointed out, chaff is not to jam but to confuse and probably overload the radar by providing multiple targetsAluminium was one of the ideal choices being of the same material as the aircraft and hence having the same radar reflectivityBy the way the most of the time it is aluminised material like mylar or even paper.
