If we delete the base table of an existing view, What happens?

Nothing will happen until you try and use the view and then you will get an error stating :

Msg 208, Level 16, State 1, Procedure View_1, Line 4
Invalid object name 'dbo.Table_1'.
Msg 4413, Level 16, State 1, Line 4
Could not use view or function 'Testing_MCrosbie.dbo.View_1' because of binding errors.
