The speed of sound in air is about 330 meters/second. In water it is much more. That would mean that the wavelength would decrease when going from water to air because the frequency would stay the same.
speed in air < speed in water.
wavelength in air < wavelength in water.
The variation is direct.
Answer:+1/2 and -1/2.
Explanation:the presence of an external magnetic field (B0), two spin states exist, +1/2 and -1/2.
The magnetic moment of the lower energy +1/2 state is aligned with the external field, but that of the higher energy -1/2 spin state is opposed to the external field.
