Question

Need help answering these questions.

Use the below information to answer Questions 15 – 17.
As shown below, the left end of a horizontal string is attached to an oscillator and the right end is attached to a wall.
The string's midpoint is labeled C, and a dot has been painted on the left half of the string. The left half of the string is
uniformly thick, with diameter Do, while the right half of the string gradually increases in thickness from the midpoint C
to the wall. The string is made of consistent, uniform material.
Wall
Do
Dot
Oscillator
Note: Figure not drawn to scale.
The oscillator shakes the left end of the string up and down with uniform frequency, creating waves traveling to the
right with a speed Vo. A student observes that every wave crest approaching the midpoint C passes through C, but
gradually slows down on the right half of the string.
(15) On which half of the string, if either, do the waves have a longer wavelength?
Left Half
Right Half
Same Wavelength on Both Halves
Briefly justify your answer with explanations of wave phenomena.
