Is this the entire question, as written, in your book?
The formula for calculating distance using echo time is distance = speed of sound x echo time / 2. This formula assumes that the sound waves are traveling at a constant speed and that the echo time is the total time from when the sound was emitted until it was received back.
The speed of sound used in the distance calculation depends on the medium through which the sound is traveling. In air at sea level, the speed of sound is approximately 343 meters per second. However, in different mediums such as water or steel, the speed of sound can vary.
Yes, you can use any type of sound wave as long as it is capable of being emitted and received back. However, some sound waves may be better suited for certain distances or mediums. For example, low frequency sound waves may travel further in water compared to high frequency sound waves.
No, you do not need specialized equipment. Any device that can emit a sound and record the time it takes for the echo to be received back can be used. This could include a stopwatch or a smartphone with a sound recording app.
Yes, there are some limitations to using echo time for distance calculations. The accuracy of the calculation depends on the speed of sound being constant and the echo time being an accurate measure of the total time. In addition, other factors such as interference or reflections can affect the accuracy of the distance calculation.
