5. This next step is going to take some skill and some careful observation. The wave speed is associated
with the movement of crests and troughs along the medium. Faster waves will have crests that move from
the left side of the screen to the right side of the screen in less time; that is the crests move from left to right
faster. Set the animation to a low frequency (about 0.1 Hz) and observe the wave speed. It might help to put
your finger or a pen cap on a crest and follow move your finger (or pen cap) from left to right along with the
crest. Then repeat for a high frequency (about 1.0 Hz). Make the same observation of wave speed - the
speed of the crest moving from left to right across the screen. Does this ten-fold increase in frequency - from
about 0.1 Hz to about 1.0 Hz - have any noticeable and appreciable effect upon the wave speed? Explain
your answer and discuss your observations.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
