Wave speed is proportional to the square root of tension. Tension doubles, so the wave speed increases by a factor of sqrt 2 = 1.414
1.414 x 160 = __ cm/s
A wave pulse travels along a string at a speed of 160cm/s. Note that part a is independent and refer to changes made to the original string.
Part A:What will be the speed if the string's tension is doubled?
I was thinking that it should be 320...but i think its wrong..
