Unformatted text preview: PHYSICS 002C Lecture 06 April 10, 2009 Serway and Jewett Chapter 13 – Mechanical Waves DEMO: Domino wave. Q: The dominoes in my domino wave machine have a height s = 5 cm. Suppose that after being tilted by its neighbor each domino falls over in a time g s t / 2 = . If the spacing between dominos is half the domino height, what is the domino wave speed in m/s? a) 1.2; b) 4.1; c) 0.25; d) 0.50; e) 0.05. New Material - Chap 13.5 – Reflection and transmission of waves At a rigid boundary a wave on a string is reflected out of phase because of Newton’s 3 rd law – To every action there is an equal and opposite reaction. The rigid boundary provides the equal and opposite reaction to send the wave back inverted. At a free end a wave on a string is reflected in phase because the motion of the string is not impeded. Imagine that our string is infinitely long and that two identical wave impulses pass each other, overlapping for an instant at the position where the real boundary would be. position where the real boundary would be....
