A stretched string of length 0.60 m is fixed at both ends. It vibrates in a standing‑wave pattern that shows three complete loops (three antinodes). The frequency of the source is 150 Hz and the linear mass density of the string is 0.020 kg m⁻¹. (i) Determine the wavelength of the wave on the string. (ii) Find the speed of the wave. (iii) Calculate the tension in the string.

Answer Options

A. λ = 0.50 m; v = 75 m s⁻¹; T = 112.5 N
Correct Answer B. λ = 0.40 m; v = 60 m s⁻¹; T = 72 N
C. λ = 0.30 m; v = 45 m s⁻¹; T = 54 N
D. λ = 0.20 m; v = 30 m s⁻¹; T = 18 N
Correct Answer
B
Correct Option:
λ = 0.40 m; v = 60 m s⁻¹; T = 72 N
