Question

a 2.00 m long string transmits waves at 12.9 m/s what is the fundamental frequency for standing waves in this string

Answer 1

`\huge\boxed{\sf f=3.225 \ Hz}`

Step-by-step explanation:

Given data:

Length = L = 2 m

Speed = v = 12.9 m/s

Required:

Fundamental frequency = f = ?

Formula:

`\displaystyle f =(v)/(2L)`

Solution:

Put the given data in the above formula.

`\displaystyle f = (12.9)/(2(2)) \\\\f=(12.9)/(4) \\\\f=3.225 \ Hz\\\\\rule[225]{225}{2}`
