Answer: sqrt(Temperature).
- A Temperature
- B sqrt(Temperature)
- C 1/Temperature
- D Temperature<sup>2</sup>
Correct answer: B. sqrt(Temperature)
Explanation: v = sqrt(gamma*R*T/M). Speed is proportional to sqrt(T) (absolute temperature).
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.
