Sonar works by sending a sound signal out. If there is an object in the way of that signal it will reflect off that object and return. The time it takes for the signal to return helps us know where the object is.
If a sonar receiver records a time of .16s and the velocity of sound in water is 1500 m/s, how far away is the object that caused the reflection?
a)
240 m
b)
150 m
c)
220 m
d)
110 m
