Question: A sonar generator on a submarine produces periodic ultrasonic waves
A sonar generator on a submarine produces periodic ultrasonic waves at a frequency of 2.50 MHz. The wave-length of the waves in seawater is 4.80 x 10-4 m. When the generator is directed downward, an echo reflected from the ocean floor is received 10.0 s later. How deep is the ocean at that point?
Answer to relevant QuestionsThe range of sound frequencies audible to the human ear extends from about 20 Hz to 20 kHz. If the speed of sound in air is 345 m/s, what are the wavelength limits of this audible range? Fred strikes a steel train rail with a hammer at a frequency of 2.50 Hz, and Wilma puts her ear to the rail 1.0 km away. (a) How long after the first strike does Wilma hear the sound? (b) What is the time interval between ...If the wavelength of the third harmonic on a string is 5.0 m, what is the length of the string? You are setting up two standing string waves. You have a length of uniform piano wire that is 3.0 m long and has a mass of 0.150 kg. You cut this into two lengths, one of 1.0 m and the other of 2.0 m, and place each length ...A 2.0-kg mass resting on a horizontal frictionless surface is connected to a fixed spring. The mass is displaced 16 cm from its equilibrium position and released. At t = 0.50s, the mass is 8.0 cm from its equilibrium ...
