Answer :
Answer:
1. 4 s 2. 0.25 Hz 3. wavelength 4. The height the object moves up and down increases
Explanation:
1. Period, T = total time/number of oscillations
total time = 60 s, number of oscillations = 15
T = 60 s/15 = 4 s
2. Frequency, f = 1/T = 1/4 = 0.25 Hz
3. The wavelength, λ. Since the velocity v = fλ
4. If he amplitude of the ocean waves increase and all other wave characteristics, the height the object moves up and down increases. This amplitude of the wave is independent of all the other properties of the wave.
