17. While looking at waves in a ripple tank you note that with the strobe disc adjusted so that the wave appear to “stand still” the wavelength is measured to be 3.50 cm +/- 0.50 cm and the strobe, which contains 6 slits, rotates 10 complete times over a

period of 7.3 sec +/- 0.5 seconds:

a. What is the frequency of these waves?

b. What is the estimated error on this frequency?

c. What will be the measured speed of the wave?

d. What is the estimated error on this speed?
