Two pulses are moving in opposite directions at 1.0 cm/s on a taut string, as shown in Fig. E15.34. Each square is 1.0 cm. <IMAGE> Sketch the shape of the string at the end of 7.0 s.

검증된 단계별 안내

Identify the initial positions of the two pulses on the string. Assume the left pulse is at position x1 and the right pulse is at position x2.
Determine the direction of movement for each pulse. The left pulse moves to the right, and the right pulse moves to the left, each at a speed of 1.0 cm/s.
Calculate the distance each pulse will travel in 7.0 seconds. Since the speed is 1.0 cm/s, each pulse will move 7.0 cm in 7.0 seconds.
Determine the new positions of the pulses after 7.0 seconds. The left pulse will be at position x1 + 7.0 cm, and the right pulse will be at position x2 - 7.0 cm.
Sketch the shape of the string by placing the pulses at their new positions. Ensure that the pulses maintain their original shape and size as they move along the string.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Wave Superposition

Wave superposition is the principle that when two or more waves overlap, the resultant wave is the sum of the individual waves. This concept is crucial for understanding how the pulses interact as they meet on the string, affecting the shape of the string at any given time.

Wave Propagation

Wave propagation refers to the movement of waves through a medium. In this scenario, each pulse travels at a constant speed of 1.0 cm/s in opposite directions. Understanding this helps predict the position of each pulse after a given time, which is essential for sketching the string's shape.

Time Calculation

Time calculation involves determining the position of the pulses after a specific duration. Given the speed and direction of the pulses, calculating their positions after 7.0 seconds allows us to sketch the string's shape accurately, considering the initial positions and movement.

교과서 질문

A fellow student with a mathematical bent tells you that the wave function of a traveling wave on a thin rope is y(x,t)=(2.30mm)cos[(16.98 rad/m)x+(742 rad/s)t]y(x,t)=\(\left\)(2.30\(\operatorname{mm)}\]\cos\)[\(\left\)(16.98\(\text{ }\)rad/m\(\right\))x+(742\(\text{ }\)rad/s\(\right\))t]. Being more practical, you measure the rope to have a length of 1.35 m1.35\(\text{ m}\) and a mass of 0.00338kg0.00338\(\operatorname{kg}\). You are then asked to determine the following: (f) tension in the rope; (g) average power transmitted by the wave.
