    A. Wavelength shortens.

    B. 3m/1.5s = x/(60x60x60) =x/216000 (there are 216000 seconds in an hour).

    Now solve for x

    Remember the relation: Wavelength X frequency = Velocity which is constant in a given medium. So, if frequency increases, wavelength decreases proportionately.

    Period = 1/frequency and frequency = 1/period

    Velocity = 3 X 5 = 15 m

    A) as the frequency increases the wavelength gets shorter and shorter, so the pitch gets higher.

    B) If this is your homework, im not helping you.

    Nu equals speed divided by wavelength

    v = lamda/T

    v=3/(1/5)

    v=15m/s
