a guitar string is 75cm long,calculate the wavelength of its fundamental note

Answer 1

In guitar, L= 1/2 lambda ;
=75/2 =37.5cm

Answer 2

L=wavelenght/2 therefore:21(wavelenght) wavelenght=2 multiplied by 75 which gives 150

Answer 3

l = landa/2
: landa = 2 * l
2 * 75 = 150cm

Answer 4

Landa=2l( for a plucked string)
Where l = 75
Fⁿ = 2×75
= 150
