What adjustments would you make for tuninga stringed instrument for it to emit a note of desired frequency?

In string instruments, tuning of frequency is done by adjusting the tension T in the string and length of the vibrating part of the string.
In string instruments , wavelength λ of the sound wave produced by string is given as

λ = ( 2 / n ) ............................ (1)
where n is number of harmonics

frequency f of sound wave ,  f = v / λ .............................. (2)

where v is velocity of transverse wave in string .Velocity v of transverse wave in string is given as

................................... (3)
where T is tension in the string and μ is linear mass density ( mass per unit length )

From eqn.(1) and (2) , we get

f = n × ( v / 2

From above expression , we know that frequency depends on velocity v of transverse wave in the string and lenegth .
velocity of transverse wave in the string is proportional to square root of tension T in the string.

Hence tuning of instrument to get desired frequency is done by adjusting tension T and length of vibrating part of string .
