A RipStik was swizzled ("wiggled") across an airport parking lot. The sinusoidal swizzle wave can be seen in the diagram below.
λ = _________ _________ Determine the wavelength λ of one wave of the RipStik swizzle wave.
a = _________ _________ Determine the amplitude a of the RipStik swizzle wave.
τ = _________ _________ The RipStik took a duration of 0.60 seconds to travel the 80 centimeters seen on the diagram above. Determine the period τ for the RipStik swizzle wave.
f = _________ _________ Calculate the RipStik swizzle wave frequency f.
ѵwave = _________ _________ Use the wavelength λ and frequency f to calculate the velocity ѵwave of the RipStik swizzle wave.
