Graph A Graph B Displacment vs. Position for Random Wave Displacement vs. Time for Random Wave -4 Position (m) Time (s) What is the frequency of the wave represented by these two graphs? Your answer:

​Two wave pulses on a string, each traveling 2 cm/s, are approaching each other. The first diagram below shows the shape of the string at time = 0 seconds. Draw what the string looks like at t = 1 second on the next graph. The axes are in cm.

A wave on a string is described by D (z, t) = (2.2 cm) x sin [27 (z/ (8.4 m) + t/ (0.20 s) + 1)]. where I is in m and t is in S. Submit Correct Part D What is the wave number? Express your answer with the appropriate units. k = 0.75 Previous Answers Submit Part E rad m Previous Answers Correct Correct answer is shown. Your answer 0.748 m required for this part. At t= 0.70 s, what is the displacement of the string at z = 9.1 m?

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.90 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m. The fisherman sees that the wave crests are spaced 7.80 m apart. Part A How fast are the waves traveling? v = 1.34 m/s Submit Part B Previous Answers Correct Correct answer is shown. Your answer 1.345 m/s was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. What is the amplitude of each wave? A = 0.310 m Submit Previous Answers Review | Constants Correct <

Question 7 Naturalists discovered a new species of rodent that lives in caves. The rodent's eyes do not function. Instead, it emits high pitched sounds and uses the reflections of those sounds to find its way around. What term best describes how the new rodent navigates its world? A intensity B echolocation C harmonics D Doppler effect
