1.you shake a rope to generate a travelling wave. If the end of the rope is not fixed, what is the phase difference of the reflected wave?
2.when we draw a sine wave to indicate a longitudinal sound wave, what does it actually represent?
Homework Answers
1) phase difference between incident and reflected wave will be zero as the particle will not have any force at the end to change its phase.
2) the sine wave will represent the pressure variations from zero upto a highest pressure (amplitude ) in the medium. The pressure variation will have sinudoidal varying relation with distance in the medium.

1. Travelling Waves A transverse wave travels along the length of a rope. The vertical displacement of any mass element of the rope is given by the function y(x.t) - 2sin(x+t+) in units of centimeters. Answer the following: () What is the velocity of the wave itself (indicate direction of motion as well)? (ii) Find the maximum transverse acceleration of the rope.

You notice your classmate is oscillating the free end of a taut rope in a simple harmonic vertical oscillation with a frequency of 3.333 Hz and amplitude 5.5 cm. At time t = 0 the end has maximum negative displacement. If the wave speed is 11.1 m/s. a) Write a wave function describing this wave and identify the amplitude, period, wavelength, an phase constant of this wave. b) At t = 0 what is the vertical displacement of the rope...

For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 226 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 42.0 m long and the whistle is located 14.0 m from one end....
