It would make sense that it would increase because there would be more crests or troughs per second, meaning the frequancy is increased. One might be inclined to say that it would double, however, we do not know the exact amount of increase.

Yes it will increase but if the wavelength is 1/2 then the frequency is doubled. 2/2 = 1 so the velocity is the same.

Yes this answer should be doubled. since v=f*wavelength if wavelength shortens by half shouldnt f double?
