First problem: Do you have a textbook? What is the equation for the period of a wave?

Second problem: How many values of what pass through a given point?

Wavelength of the wave = 15 cm = 0,15 m

Velocity of the wave = 60 m/s

Wavelength . Frequency = Velocity

0,15 m . f = 60 m/s

f = 400 /s

Period is 1/f, i. e., T = 1/f

T = 1 / 400 /s

T = 0,0025 s

how many values pass through a given point in a guitar of a given minute?
