If the pitch of a sound is increased, what is its effect on:

a. Frequency – Increases, as pitch is directly related to frequency.
b. Speed – Remains the same in a given medium.
c. Intensity – No direct relation, but higher frequencies may seem louder to human ears.
d. Loudness – Not necessarily affected, as loudness depends on amplitude.
e. Wavelength – Decreases, as frequency and wavelength have an inverse relationship.
