Concept: The frequency won't change in water or in air.
Since wavelength x frequency = speed, wavelength is proportional to speed.
So, Middle C has a longer wavelength in water than in air.

Oh gosh oh I see it in my life face and
Answer:
11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec
7.02 mi/sec * 3600 sec / hr = 25,300 mph
Answer:
A: has a shorter wave length
Explanation:
As we know that the there is no relation between the frequency and the ampitude. But there is an inverse relation with respect to the wavelength i.e. if one is rise than the other would decrease. In addition to this, the shorter the
wavelength, the smaller would be the frequency and vice versa.
So if X contains the greater frequency so it has a shorter wave length
hence the option A is correct
