Answer #1

given

frequency f = 20.6Hz

amplitude = A = 8.26cm/2 = 4.13cm

   from the figure λ/2 = 5.20cm

    λ = 2 * 5.20cm = 10.40cm

time period = T = 1/f = 0.0485s

   speed of the wave v = fλ = 20.6Hz * 10.4m = 214.24m/s

> for the last answer you have to convert from cm/s to m/s to get the correct answer
