A person blows into open-end of a long pipe. As a result, a high-pressure pulse of air travels down the pipe. When this pulse reaches the other end of the pipe,
- a high-pressure pulse starts traveling up the pipe, if the other end of the pipe is open.
- a low-pressure pulse starts traveling up the pipe, if the other end of the pipe is open.
- a low-pressure pulse starts traveling up the pipe, if the other end of the pipe is closed.
- a high-pressure pulse starts traveling up the pipe, if the other end of the pipe is closed.
Answer
(A) a high-pressure pulse starts traveling up the pipe, if the other end of the pipe is open.
