PHYS 1403 Lab Homework Waves This homework will be due when you come to lab the week of May 1. l) A pulse of the shape shown below propagates to the right along a string with velocity Describe in detail the motion of particle A on the string as the pulse goes by. Be sure to indicate (i) the direction in which A is moving at various points along the pulse (ii) and whether the velocity of A is increasing, decreasing or zero at these various points 2) The diagram below shows two pulses on a string at time t 0. 10.0 5.0 x (m) 5.0 10.0L The pulses are moving toward each other, the speed of each pulse is 2.5m/s. ON A SEPARATE SHEET OF GRAPH PAPER sketch the shape of the string at 0.60, 0.80 credit.) (Graphs sketched on notebook paper rather than graph paper will receive no

Explanation / Answer

distance between two consecutive nodes.

d = lamdba / 2

lambda = 2 ( 6 cm ) = 12 cm

Wavelength = 12 cm .........Ans

distance between consecutive node and antinode = lambda / 4

= 3 cm

positions of antinodes = 3cm, 9cm , 15 cm ........Ans
