What is the total distance traveled by ultrasound in echo-ranging if the speed of sound through seawater is v and the time interval between transmission and reception is t?
What is the total distance traveled by ultrasound in echo-ranging if the speed of sound through seawater is v and the time interval between transmission and reception is t?
- $2v \cdot t$ (correct)
- $\frac{v}{t}$
- $v + t$
- $\frac{v}{2} \cdot t$
Why can't ordinary sound of longer wavelengths be used for echo-ranging purposes?
Why can't ordinary sound of longer wavelengths be used for echo-ranging purposes?
- It travels too fast through seawater.
- It gets absorbed by icebergs.
- It reflects poorly from underwater hills.
- It bends around corners and enters the detector. (correct)
