7.6 m
Figure 1
The technician has a device that can emit and detect ultrasound.
The device emits a pulse of ultrasound towards the wall and detects the echo of
the pulse a short time later.
The wall is 7.6 m from the device.
The speed of ultrasound in air is 330 m / s.
Calculate the time between the emission of the pulse and the detection of
the echo.
