You and your lab partner pull a slinky across the hallway floor so that it is stretched out to 10.0meters. Your partner shakes one end through five full cycles in two seconds. The first wave peak reaches you 0.50s after starting to shake. a) What is the wave speed? b) What is the frequency and wavelength? c) You tied your end of the slinky to a heavier rope under the same tension as the slinky. The new medium has twice the mass per unit length as the slinky. What is the new wave speed? d) What is the wavelength and frequency in the new medium?

    A wave pulse travels down a slinky. The mass of the slinky is m = 0.94 kg and is initially stretched to a length L = 7.4 m. The wave pulse has an amplitude of A = 0.23 m and takes t = 0.412 s to travel down the stretched length of the slinky. The frequency of the wave pulse is f = 0.45 Hz. 3)What is the average speed of a piece of the slinky as a complete wave...

    For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 226 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 42.0 m long and the whistle is located 14.0 m from one end....
