Good question! The wavelength of some waves is longer than the diameter of the tube, and other wavelengths easily fit the tube dimensions. This means they will use different propagation methods along the tube, depending on frequency. [the experts call this a 'frequency dispersive medium'] . The ping is a descending note , so the higher frequencies ( = shorter wavelengths) are reflected first.
You may observe a similar effect with an echo from a corrugated iron fence.

Sound travels at 1530 meter per second in water. If a submarine searching for an enemy vessel sends out a sonar ping and receives an echo back in 20 seconds. How far away is the other sub?
30,600 meters.
How can we measure the depth of sea by using SONAR?
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
What do the parameters reported back by ping of time and TTL represent?
When you ping an ip address you receive a return from your 'echo request' you can get a multitude of response depending on which 'switches you use' by default windows/DOS returns bytes transmitted time - in milliseconds - the transmission took RTT = round trip time TTL = Time To Live (max 255)
What are sound wave best reflected of?
Sound waves travel best through solids because the particles are closer together With respect that's not what was asked. Reflection occurs at the boundary between two media of very different densities hence sound-transmitting speeds. E.g. a brick wall echoing the sound back in air; or the sea-bed reflecting the "ping" of an echo-sounder placed in the water under a ship's hull. It can also occur on haloclines and thermoclines in the sea, because they are sharp changes in the water's density given by differences in salinity and temperature respectively. The sharper the boundary the better its reflectivity, all other things being equal.
Why the ttl change in the same ping?
You have multiple routes between you and your ping target.
What are the release dates for Campus Security - 2012 Stop Clap-ping 1-3?

How does an echo sounder determine the depyh of water?
An echo sounder measures water depth by sending a sound wave (ping) from a transmitter down to the seabed. The sound wave reflects off the seabed and returns to the echo sounder, which calculates the time it takes for the signal to return. By knowing the speed of sound in water, the echo sounder can determine the depth of the water based on the time taken for the signal to return.
What is the command that test connectivity by sending an echo request to a remote computer?
Ping
What will the -n switch do when used with the Ping command?
Running the ping command with -n "count" is the number of echo request to send.
What is pinging sound?
It is a sound that goes 'ping!'
Which command sends an echo request packet to an address and then waits for a reply?
ping
How you autorun a batch file?
you can autorun a batch file using another batch file which will make it go off after a certain amount of time heres what you should do: @echo off color0a echo 5 ping localhost -n 2 >nul cls echo 4 ping localhost -n 2 >nul cls echo 3 ping localhost -n 2 >nul cls echo 2 ping localhost -n 2 >nul cls echo 1 ping localhost -n 2 >nul cls echo 0 ping localhost -n 2 >nul cls ((((note you can make this time longer if u notice the pattern))))(delete me) start (location of file here) to find file location right click on desktop click new>shortcut> search for file>click ok>copy the link>close the shortcut via the X>paste it in there times autorun
How to work ping?
The "ping" program uses ICMP echo message requests and listens for ICMP echo message reply messages from its intended host. Using the -R option with ping enables the record route feature. If this option is used ping will set the record route (RR) in the outgoing ICMP IP datagram. Website:http://www.iyogibusiness.com/
When you use a ping command in microsft if its successful 5 exclamations are displayed whereas it is different on cisco why?
The ICMP protocol is standardized, in the sense that a computer should reply with a certain message (called "echo-reply") if it receives a certain other message (the "echo-request"). How many echo-request messages are sent when the user types "ping" is NOT standardized - there is no need to.The ICMP protocol is standardized, in the sense that a computer should reply with a certain message (called "echo-reply") if it receives a certain other message (the "echo-request").

What is the definition of ping?
The sound made by a bullet in striking a solid object or in passing through the air., To make the sound called ping.
What is an echo-request?
An echo-request is a sort of ICMP (Internet Control Messaging Protocol). This protocol is used to check and control the IP packet traffic.For example, ping and traceroute packets are echo requests.
