A copper cable is tied between two trees. The horizontal distance between the two trees is 3 m. The transverse waves travel at a speed of 80 m/s along the taut cable. Calculate the i) wavelength and ii) frequency of the third overtone.

• A. i) λ = 0.75 m ii) f = 53.3 Hz
• B. i) λ = 0.75 m ii) f = 106.6 Hz
• C. i) λ = 1.5 m ii) f = 53.3 Hz
• D. i) λ = 1.5 m ii) f = 106.6 Hz

Answer: (C)
