Ripples radiate out from vibrating source in water. After 6.00 s, 42 ripples have been generated with the first ripple covering a distance of 3.00 m from the source (each ripple constitutes a wave).
What is the wavelength of the ripples? (a) 0.048 m
(b) 0.071 m (c) 0.43 m (d) 3.0 m
What is the frequency of the ripples? (a) 14 Hz
(b) 7.0 Hz (c) 0.33 Hz (d) 0.17 Hz
What is the speed of the ripples? (a) 0.1 m s−1
(b) 0.2 m s−1 (c) 0.4 m s−1 (d) 0.5 m s−1
