Question 6
In a Physics lesson, Mr. Wong demonstrates wave motion using a slinky. One
end of the slinky is fixed to the wall, while the other end is moved repeatedly from
side to side. This motion produces a wave that propagates along the slinky with
a constant speed. The diagram below represents the slinky at a particular instant
in time.
a. On the diagram below, indicate a compression by labeling it with C, and a
rarefaction by labeling it with R. [1 mark]
b. On the same diagram, identify and mark a distance equivalent to one
wavelength, and denote it with the symbol λ. [1 mark]
c. If Mr. Wong doubles the speed of his hand movement, what effect will this
have on the wavelength? What does this observation reveal about the
relationship between wavelength and frequency? [2 marks]
d. Provide one real-world example of a wave that resembles the motion of the
slinky. [1 mark]
