1)A longitudinal wave with a frequency of 34 Hz takes 1.0 s to travel the length of a 2.5 m Slinky (see the figure). Determine the wavelength of the wave. λ = (    )m

 2) In the figure below, the hand moves the end of the Slinky up and down through 2 complete cycles in 1seconds. The wave moves along the Slinky at a speed of 0.60 m/s. Find the distance between two adjacent crests on the wave.

3) The mass of a string is 4.20  10-3 kg, and it is stretched so the tension in it is 135 N. A transverse wave traveling on this string has a frequency of 260 Hz and a wavelength of 0.60 m. What is the length of the string?

4) A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the wavelength of the sound.

5) When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 7.5 km/s and the secondary, or S, wave has a speed of about 3.0 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 200 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?

6) A string has a linear density of 7.20  10-3 kg/m and is under a tension of 390 N. The string is 1.9 m long, is fixed at both ends, and is vibrating in the standing wave pattern shown below in the drawing.
