You are in Switzerland and decide to try yodeling. You are facing a cliff some distance away. If the speed of sound is 340 m/a and you hear the echo 1.5 seconds after you begin to yodel, how far away is the cliff? The sound travels to the cliff and back during the 1.5 seconds. B) If your yodel is at frequency 600 Hz, what is the wavelength of the sound?

Young's modulus for steel is 20*10^10 N/m^2 and the density is 7.8*10^3 kg/m^3. The bulk modulus for water is 2.2*10^9 N/m^2 and the density is 1.0*10^3 kg/m^3 A. What is the speed of sound in steel ? B. What is the speed of sound in water ?

Ultrasound reflected from an oncoming bloodstream that is moving at 33.0 cm/s is mixed with the original frequency of 1.50 MHz to produce beats. What is the beat frequency (in Hz)?

A student takes a 30.00 - m - long string and attaches one end to the wall in the physics lab . The student then holds the free end of the rope , keeping the tension constant in the rope . The student then begins to send waves down the string by moving the end of the string up and down with a frequency of 2.00 Hz . The maximum displacement of the end of the string is 20.00 cm . The first wave hits the lab wall 6.00 s after it was created . ( a ) What is the speed of the wave ? ( b ) What is the period of the wave ? ( c ) What is the wavelength of the wave ?
