A 100 cm long string fixed at its two ends is plucked from the middle. The wavelength of stationary waves generated is:
Correct answer: C. 2m
- A. 0.5 m
- B. 1m
- C. 2m
- D. 3m
Explanation
A string fixed at both ends with length L = 1 m supports fundamental λ = 2L = 2 m. Plucking at midpoint excites harmonics including the fundamental, giving λ = 2 m.
