(13%) Problem 8: A wire is oscillated to create a wave of the form y(x,t) = Asin(x - 30t) == The wave is reflected from a fixed end producing a reflection of the form y2(x,t) = A sin(x + 30t) The two waves interfere to create a standing wave. 20% Part (a) What is the minimum length of wire required to do this? L_min=1.000 m Correct! 20% Part (b) If the actual length of the wire is 3.0 m, how many antinodes are formed by the standing wave? n = 3.000 Correct! 20% Part (c) How far from the left end (call this the origin) is the first antinode? x=0.5000 m Correct! 20% Part (d) How far from the left end is the second antinode? x=1.500 m Correct! 20% Part (e) How far from the left end is the first point at which the amplitude of the standing wave is equal to the amplitude of the original wave (A)? x = 1 m Grade Summary Deductions 0% (13%) Problem 8: A wire is oscillated to create a wave of the form y(x,t) = Asin(x - 30t) == The wave is reflected from a fixed end producing a reflection of the form y2(x,t) = A sin(x + 30t) The two waves interfere to create a standing wave. 20% Part (a) What is the minimum length of wire required to do this?
