Answer: Both A and C.
- A sqrt(tension)
- B tension
- C 1/sqrt(linear mass density)
- D Both A and C
Correct answer: D. Both A and C
Explanation: v = sqrt(T/mu) where T is tension and mu is linear mass density. Speed depends on sqrt(T) and 1/sqrt(mu).
A standing wave forms from two identical waves travelling in opposite directions and interfering; nodes (always zero displacement) and antinodes (maximum displacement) stay fixed in place, unlike a travelling wave where the whole pattern moves.
Concept context
Wave types, superposition, standing waves, Doppler effect, and sound intensity.
