_______________ The data sheet handout 092 fall 2008 - spring 2011 has a graph based on 75 measurements of echoes from fall 2008 to spring 2011. Based on the graph on that handout, what is the experimental speed of sound?
________________ Given that the theoretic speed of sound is 348 m/s, what is the percentage error for the experimental speed of sound above?
________________ The above data suggests which of the following is true over the past three years: the clapping is too fastORthe clapping is too slow?
______________ Given a theoretic speed of sound of 348 m/s, what is the flight time for an echo out and back from a wall that is 116 meters away from the clappers?

_______________ Given that the refractive index of water is 1.333, how far below the surface will a penny appear to be if the penny is actually 100 centimeters under water?
_______________ The Alfons-Ardos theory states that the image in a mirror is as far behind the mirror as the object is in front of the mirror. If the Alfons-Ardos theory is correct, for an object distance of 75 centimeters, what will be the image distance?
A RipStik was ridden across a wet cloth towel soaked in water with food color. The RipStik was then swizzled across a large sheet of presentation paper. The swizzle wave can be seen in the diagram below.
λ = _______________ Determine the wavelength λ of the RipStik swizzle wave.
a = _______________ Determine the amplitude a of the RipStik swizzle wave.
τ = _______________ The RipStik took a duration of 1.36 seconds to travel the 68 centimeters seen on the diagram above. Calculate 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.
