I put my iphone on silent, will it still buzz?

I lost my iphone at school today and I'm freaking out. I called it a couple of times and I had people text it for me so I'm curious on whether or not it'll buzz? Also if there's any way to locate it then please tell me! I haven't set it up on iCloud yet because I JUST got it recently and I use Windows mostly so it wasn't a big thing for me.

Also is there anyway for a caller to know that your phone is on airplane mode? I think I turned airplane mode off on my phone but I might have turned it on again since I was at school.

It should buzz on silent, and airplane mode has this orange airplane on the top

You could use track my iphone app if you have an ipod or ipod or another iphone. Just hope your iphone has location services on and trackmyiphone on to. Also yes it still buzzes. Though its not very loud. Good luck! And no there's no way to find out if its on airplane mode. But if its on then well your *** lol sorry.
