What was your answer from example number 2?

**WE were given v and Wavelength so we can use the original formula

v= (wavelength)( f)

65 m/s= (0.8 m)(f) You want to solve for f so divide.

65/ 0.8 = f

81.25 seconds = f

Work

v=65 m/s
wavelength =0.8 m
f=?

Given

Answer from example number 2

From here on out. I want to see what you can do so I will not be helping.
