1. Consider a wave that has a frequency of 6.1 kHz and a wavelength of 0.11 m. Write an equation that might describe this wave. (Assume that the amplitude is 1 m and the wave propagates in the positive x direction. Use the following as necessary: x, t, and ?.)
2. A radar system can measure the time delay between the transmitted and reflected wave pulses from a distant airplane with an accuracy of 1.02 picoseconds. What is the accuracy in the calculated distance to the plane?
3. You are studying guitar strings and are able to measure a few of (but not all) the standing wave frequencies for a particular string. If you measure frequencies of 360 Hz, 600 Hz, 840 Hz, and 1080Hz, what is the highest possible value for the fundamental frequency?
