If the mass per unit length of a violin string was quadrupled without changing the string's tension, the speed with which a wave (produced by the player's bowing action) travels on that string would
-become four times its former value.
-become one half of its former value.
-become two times its former value.
-become one quarter of its former value.
-not change.
Homework Answers
- become one half of its former value.
Note- velocity of wave on string is proportional to square root of inverse of mass per unit length. Therefore, by increasing mass per unit length four times would change velocity half of its initial value.
