Problem 8DQ

An echo is sound reflected from a distant object, such as a wall or a cliff. Explain how you can determine how far away the object is by timing the echo.

Step-by-Step Solution:

Solution 8DQ Step 1: The sound waves are formed due to vibrating matter , the sound waves travel through matter , when these sound waves hit different material they are reflected by the by the surface of the material This reflected waves act as echo The distance of the object is determined using d = v × t Here d distance of the object v velocity of the sound waves t time taken by reflected waves Using the above equation we can determine the distance of the object which is reflecting the sound waves and causing echo
