A hiker hikes to a canyon and yells "hello" into the canyon wall. She carefully times how long it takes for the sound to return to her ear. She hears her echo in .6s. With a known velocity of sound on this day of 340m/s, how far did the sound wave actually travel?

The distance covered by the sound wave is 102 m.

Explanation:

The velocity of sound on a particular day, v = 340 m/s

The echo heard by a hiker is, t = 0.6 s

The distance covered by the sound after hearing an echo is 2d say. The speed of sound is then given by :

So, the distance covered by the sound wave is 102 m.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
