This is a picture of two guitars in my house. Guitars can play a wide range of notes, or frequencies. We learned that the formula for a string's frequency is: f=v/2L. Coupled with the V=sqrt F/m/l equation, we can explain why increasing the tension increases the frequency: if force (tension) is increased, then velocity is also increased, and therefore, frequency is increased. You can also shorten the length of the string played, and decreasing the length will also result in a higher frequency.
I could apply the physics knowledge in this blog and become the next Jack Johnson.
