If the frequency of a sound wave propagating through a uniform medium is doubled and its amplitude is halved, how do the pitch and loudness of the sound change?

Options:

• A: Pitch is halved, and loudness is doubled.
• B: Pitch is doubled, and loudness is reduced to one-fourth of its original value.
• C: Pitch is doubled, and loudness is reduced to half of its original value.
• D: Pitch remains unchanged, and loudness is reduced to one-fourth of its original value.
