A. Find the tension in a 60 cm guitar string that has a mass of 1.4 g if it is to plug the note G with a frequency of 396 Hz. Assume that the wavelength of the note will be two times the length of the string. B. Waves in a lake are spaced 5.00 m and pass an anchored boat 1.25 sec apart. (a) How long before a particular wave crest can return to pass underneath a boat a hundred meters away from the shoreline? (d) if we will stay longer to see the boat tossed up and down a hundred times, how long will we have to wait? C. Light waves travel in a vacuum at a speed of 300 000 km/s. (a) The frequency of the longest visible red light is 4 x 10^8 MHz, what is its approximate wavelength? (b) The wavelength of the shortest ionizing gamma radiation is in the order of 1 x 10^-5 nm, its frequency is about? D. A fisherman notices that his boat is moving up and down in a periodic way 5 points because of the waves on the surface of water. It takes 4.0 seconds for the boat to travel from its highest to its lowest point, a distance of 3.0 meters. The fisherman sees that the wave crests are spaced 8.0 meters apart. (a) What is the amplitude, wavelength and period of the wave? (b) How fast are the waves traveling?
