Explanation / Answer

T = tension

f = frequency

L = length

n = harmonic number

Part a:
velocity = sqrt ( T / mass per unit length )

tension is increased to Tf = 4Ti

velocity increase factor 4 = 2

(f3(final ) /f3 initial) = 2

Part b:

= v/f = 2L/n

Wavelength does not vary with tension

3/ 1 = 1
