Unformatted text preview: Muraj, Hamza Homework 36 Due: May 1 2006, 4:00 am Inst: Florin 1 This printout should have 10 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. The due time is Central time. 001 (part 1 of 1) 10 points The figure below shows a complex wave pat tern on a string moving towards a rigid hook at the wall on the right. After some time, the wave is reflected from the wall. v Select the wave pattern for the reflected wave. 1. v 2. 3. v correct 4. v 5. v Explanation: Consider the wave pattern image reflected about the rigid hook on the wall. v v After the time it takes for the wave to be reflected from the wall, this image is the wave pattern traveling to the left along the string. Note: Reflection about a point (hook) is the same as reflection about the yaxis (wall) fol lowed by reflection about the xaxis (string). The leading part of the wave must remain in front and the wave is flipped over. This is the first wave pattern of four possi ble wave patterns presented by this question. 002 (part 1 of 1) 10 points An incident sine wave y i ( x,t ) = A sin( k x t ) (1) travels to the right and is reflected off a fixed end of the string at x = L . Which of the following expression gives the correct formula for the reflected wave y r ( x,t )?...
