Directions: Type your answer in the box.An object is 2 meters (m) away from an advanced cane. A sound wave from the cane would have to travel a total of m before the user is alerted that the object is present. Your answer must be a whole number.

A group of hikers hears an echo 3.50 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 343 m/s.) m

You can hear an echo when the sound wave reflects from the wall and reaches you.If you hear an echo, 4 seconds after you produce the sound, how far is the wall?Use a speed of sound of 340 m/s for this question.  340 meters away from you You Answered  1360 meters away from you Correct Answer  680 meters away from you   10 meters away from you

A sound wave has a frequency of 1.0 kHz and a wavelength of 0.33 m. What is the distancetravelled by the wave in 2.0 ms and the nature of the wave?

If the intensity of a sound wave is 10 W/m² at a distance of 5 m from the source, calculate the intensity at a distance of 20 m from the source.
