Question
For the next experiment we will be using an ultrasonic sensor. This works by
emitting a sound wave from a speaker and bouncing it off an object. The delay
between the sending and retrieval of this sound wave allows us to determine
the distance to the object. Assuming a speed of sound of 343 m/s, answer the
questions below and show your work:
o How far in centimeters does a sound wave travel in 3000 microseconds?
o How long in microseconds does it take a sound wave to travel 30 cm?
Truncate your answer to the first decimal place.
How long in microseconds does it take for a sound wave generated to
bounce and get back from an object 50 cm away?
