Problem 1: You observe that waves on the surface of a swimming pool propagate at 0.750 m/s. You splash the water at one end of the pool and observe the wave go to the opposite end, reflect, and return in 29 s. How many meters away is the other end of the pool? d = Problem 2: Sound travels at a speed of v = 1520 m's in water. While underwater a student hears a f= 2.5 kHz note In a whale song. Randomized Variables v = 1520 m's f= 2.5 kHz Part (a) Input an expression for the wavelength of the sound wave in water Aw. Part (b) What is the wavelength in meters? Aw = Problem 3: A transverse wave traveling on a Slinky@ that is stretched to a total length of 2.5 m takes 5.5 s to travel the length of the Slinky and back again. Part (a) What is the speed of the wave in units of meters per second? v = Part (b) Using the same slinky stretched to the same length, a standing wave is created which exhibits of three antinodes and four nodes. At what frequency, in hertz, must the Slinky be oscillating? f = Part (c) Since a Slinky can have traveling transverse waves on it, we can define a tension in it as if it were a string. If the total mass of this Slinky is 340 g, what is the "effective tension" in units of newtons? Teff= Problem 5: An orchestra contains both string and wind instruments. The orchestra tunes their instruments in the morning at a temperature of To = 15 .C. As they play, the temperature rises in the afternoon to TH 30 C and falls in the late evening back to Tc. As usual, the speed of sound in air increases with increasing temperature. Part (f) As the temperature drops back to To, the: Tension in the strings of the stringed instruments must be reduced to increase the frequency of the notes produced, while the lengths of the air columns of the wind instruments must be reduced to reduce the frequency of the notes produced Tension in the strings of the stringed instruments must be increased to lower the frequency of the notes produced, while the lengths of the air columns of the wind instruments must be reduced to increase the frequency of the notes produced. Tension in the strings of the stringed instruments must be reduced to lower the frequency of the notes produced, while the lengths of the air columns of the wind instruments must be increased to increase the frequency of the notes produced Tension in the strings of the stringed instruments must be reduced to lower the frequency of the notes produced, while the lengths of the air columns of the wind instruments must be reduced to reduce the frequency of the notes produced None of the above. Tension in the strings of the stringed instruments must be reduced to lower the frequency of the notes produced, while the lengths of the air columns of the wind instruments must be reduced to increase the frequency of the notes produced
