Question on Wavelength of Sound generated by a String

Waves and Sounds is one of the basic concept in Physics which deals with wavelength, frequency and velocity of waves and sounds under uniform motion.

Topic : Velocity and Wavelength of Sound

Waves travel under uniform motion in sinosoidal form. However velocity of waves will be calculated using same formula v = s/t where s is the distance between two crests of wave denoted by λ.

Question : The velocity of waves on a string is 92 m/s. If the frequency of standing waves is 475 Hz, how far apart are two adjacent nodes?

Solution :
The distance between two adjacent nodes is the half of wavelength.
Therefore:
λ = v/f
= 92/475
= 0.2m

Therefore: d = λ/2 = 0.1 m
