Hi Becca,
a) the pitch would increase as frequency increases
b) the intensity ie loudness increases since intensity is proportional to square of amplitude
Ultra sound otherwise known as ultrasonic is the sound whose frequency is beyond the audibility of human ear. Usually human ear is able to sense the frequency ranging from 20 Hz to 20 KHz. If the frequency is 25 KHz then it is known as ultra sonic. or ultra sound.
IF the velocity is more than the Velocity of sound in air medium, then such a speed is called as super sonic.
