The violin strings vibrate 544 times per second. How many vibrations are produced when the sound travels a distance x

A pipe with one closed end vibrates with standing waves at the second harmonic. It produces a C- note that has a frequency of 264 Hz. How long is the pipe? The speed of sound in air is 340 m/s. 0.97 m 1.29 m 1.61 m 0.32 m

A dolphin uses echolocation underwater to "see" its surroundings. If the speed of sound in the ocean is 1530m/s, how long would it take for the dolphin to hear an echo if the ocean floor is 2.57km below it?

A stretched string has a fundamental frequency of 780 Hz. What is the fundamental frequency if the tension is increased by a factor of 3.00?

The pan flute is a musical instrument consisting of a number of closed-end tubes of different lengths. When the musician blows over the open ends, each tube plays a different note. The longest pipe is 0.33 m long. What is the frequency of the note it plays?

A violin string of length 32.8 cm that sounds the note is under a tension of 50 N and has a mass per length of 0.6 grams per meter. How many round trips are completed per second? This tells you the frequency of the sound produced by the string.

Ultrasound of intensity 2.00 x 10-2 w/m2 is produced by the rectangular head of a medical imaging device measuring 3.00 cm by 6.05 cm. What is its power output?
