Problem 10P
Two strings are made of the same material and have equal tensions. String 1 is thick; string 2 is thin, (a) Is the speed of waves on string 1 greater than, less than, or equal to the speed of waves on string 2? (b) Choose the besi explanation from among the following:
I. Since the strings are made of the same material, the wave speeds will also be the same.
II. A thick string implies a large mass per length and a slow wave speed.
III. A thick string has a greater force constant, and therefore a greater wave speed.

III. A thick string has a greater force constant, and therefore a greater wave speed.
ANSWER:
Step 1 of 2
Part a
When the first string is thicker than the second string, the speed of wave generated in the former will be less than that of string 2.
