1. a floating object moves up and down 15 times in 60. seconds because of ocean waves. calculate the period of the ocean waves. Period (T) = total time /#oscillations counted

*60/15 = 4 T

2. calculate the frequency of the ocean waves. show your calculations and include units in your answer.

3. an additional wave property must be known in order to calculate the velocity of the ocean waves. identify the additional property.

period
frequency
wavelength
speed

4. describe what will happen to the object if the amplitude of the ocean waves increases and all other wave characteristics stay the same.

plz help, i think i have #1 correct but i need help with the rest, just trying to graduate.. will give brainliest
