Question

Select the correct answer.

How does increasing the tension of a spring affect a wave on the spring?

A.
wave velocity increases
B.
wave velocity decreases
C.
wave amplitude increases
D.
wave amplitude decreases

Answer 1

A. the velocity of the wave increases

Step-by-step explanation:

from the mathematical formular

`f= (v)/(l) =(1)/(T)=\sqrt{(T)/(k) }`

where v is the velocity, f is frequency, T is tension, l is length or wavlenght and k is constant.

from the expression you can see that when the tension increases, the velocity will also increase.

for amplitude, tension has no effect on it.
