a girl oscillating the end of a rope creates waves while travel along the rope at a fixed speed towards the right. She oscillates the rope twice each second. She watches each wave she makes travel the 4 meter long rope in one second. How long is the wavelength of the wave she is producing?
Homework Answers
SOLUTION :
In 1 sec. she competes 2 swings.
In 1 sec. wave travels 4 m
So, wave length = 4 / 2 = 2 m (ANSWER).

Adjacent antinodes of a standing wave of a string are 20.0 cm apart. A particle at an antinode oscillates in simple harmonic motion with amplitude 0.600 cm and period 0.100 s. The string lies along the +x-axis and its left end is fixed at x = 0. The string is 70.0 cm long. At time t = 0, the first antinode is at maximum positive displacement. a. Is the right end of the string fixed or free? Explain. b. Sketch...
