- Asap plzzzphysical science, please simplify When employing active sonar, a submarine emits a sonar signal that has a frequency of 320 MHz (megahertz). The speed of sound waves in ocean water is 1531 m/s. What is the wavelength of this sound wave in microns?The highest frequency that we can hear is about 20 kHz (2x 10^4Hz). a) Calculate the wavelength (m) associated with this frequency for sound that travels at 345 m/s. b) How long is this in feet? (Roundanswers to the nearest tenth.
- The figure shows the circular wave fronts emitted by two sources, the wavelength for both idential waves is 1.4 m. What is the path-length difference at point Q, in meters? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.A 2m high water wave travels past an observer. Every 3s he sees 5 full waves pass him. Each peak is 4 m apart. Calculate the: frequency,period,angular velocity,speed of the wave.D1.
- On a 20°C night, a bat hovering in the air emits an ultrasonic chirp that has a frequency of 45 kHz. It hears an echo 54 ms later. a. Suppose the bat's timing uncertainty is ±1 ms; that is, what the bat perceives as a 54 ms delay could actually be anywhere in the range 53-55 ms. What is the uncertainty in the distance to the object? b. Suppose the object is an insect flying straight away from the bat. What is the insect's speed if the ultrasonic echo is shifted down in frequency by 750 Hz?Asap plzzz1. A stone tossed into a body of water creates a disturbance at the point of impact that lasts for 4.00 s. The wave speed is 25.0 cm/s. (a) Over what distance on the surface of the water does the group of waves extend? (b) An observer counts 12 wave crests in the group. Estimate the precision with which the wavelength can be determined. Use the uncertainty relationship for classical waves. AxA. E12 where ɛ = 0.1

For the largest pe- riod T calculate the speed of the propaga- tion v. In which direction does the wave propagate (in +x or -x)? c) What is the maximal speed and accelera- tion of the points along the wave? y(m) 2 1 1 2 3 4 x(m)Is the formula to be used is v=s/t? If so the answer is 2.07 m/s. However, my teacher told me to use the wavespeed formula that lamda= 2583 cm and frequency is 0.04 Hz. However I think that is wrong. I asked her why lamda is 2583 if it clearly states that the 2583 is the length of the pool not the wave itself. She told me that wavelength and distance is the same. But still I rejected. Is wavelength and distance the same? If not how are they different
