Wavelength = (speed) / (frequency)
so in order to answer this question, we need the speed of sound.
Without using my precious time to go look it up, I'm guessing that
the speed of sound at STP is roughly 343 m/s .
If that estimate is accurate, then
Wavelength = (343 m/s) / (440 /s) = 0.78 meter .
Choice-#2 is much closer to this result than any of the others,
so choice-2 must be it.
Actually, we can 'reverse engineer' Choice-#2 and find the number
it uses for the speed of sound.
Speed = (wavelength) x (frequency)
= (0.75 m) x (440 /s) = 330 m/s .
The author of the question used 330 m/s for the speed of sound.

Answer: the momentum is increased
Energy and momentum are conserved, this was proved by he American physicist Arthur H. Compton after his experiments related to the scattering of photons from electrons (Compton Effect), in which he also proved that photons do have momentum.
So, this momentum is given by the following expression:
Where is the Planck constant and is the wavelength of the photon.
As we can see, the momentum is inversely proportional to to the wavelength. This means, if <u>decreases</u>, <u>increases</u>.
