What are echoes and what causes them?

Answer 1

Echo, also known as Ronin, is a fictional character, a Marvel Comics superheroine and a supporting character of Daredevil. She makes her first appearance in DaredevilVol. 2, #9 (Dec. 1999), and was created by David Mack and Joe Quesada. She is a Hispanic Native American and one of the very few deaf comic characters.

When she dons her "Echo" guise, she is easily recognizable by a white hand stain which covers most of her face.

The identity of Ronin was an attempt by New Avengerswriter Brian Michael Bendis to create a mystery after the apparently-male character was depicted on several comic book covers, including issues of New Avengers, and one Pulse issue. Fan speculation was high, with the most common guess that Ronin was Daredevil (despite Bendis initially denying that this was the case, he eventually revealed this to be the original intention).[1] However, Avengers: The Ultimate Guide, a DK Press book, revealed Ronin to be Echo weeks before the slightly delayed release of New Avengers #13, where Ronin's true identity was belatedly revealed.

While still a young girl, Maya Lopez's father (known as Willie "Crazy Horse" Lincoln), was killed by the Kingpin. As Crazy Horse dies, he leaves a bloody handprint on Maya's face. His last dying wish is that his partner in crime, the Kingpin, raise Maya well: a wish the Kingpin honors, caring for her as his own.

Believed to be mentally disabled, Maya is sent to an expensive school for people with learning disabilities. There, she manages to completely replicate a song on the piano. She is subsequently sent to another expensive school for prodigies. She would soon become a gifted woman.

One day, upon visiting her father's grave with Fisk, Maya asks how he died. Fisk tells her that Daredevil killed him.

Maya is sent by the Kingpin to Matt Murdock to prove Matt's weakness. He tells her that Matt believes he is a bad person, and that she is the only way to prove him wrong. As Maya believes him, it would not appear to be a lie when she tells Matt.[volume & issue needed]

Matt Murdock and Maya soon fall in love. She later takes on the guise of Echo to hunt down Daredevil. On her face she paints a white handprint, similar to the bloody handprint left by her dying father. Having watched videos of Bullseye and Daredevil fighting, she proves more than a match for Daredevil. After several failed attempts, noticing that Daredevil can easily move through the dark, Maya easily figures out Daredevil's weakness, and exploits this by having him fight in a place where his heightened senses are useless. Maya easily takes him down and nearly kills him, refusing only when she finds out Matt and Daredevil are one and the same. Matt manages to correct the Kingpin's lies. In revenge, Maya confronts Fisk and shoots him in the face, blinding him and starting the chain of events that lead to his eventual downfall (Kingpin would later partially recover his eyesight through reconstructive eye surgery).[volume & issue needed]

After realizing the Horror of her actions and the lies she has grown up with, Maya flees the United States to do some soul-searching. When she comes back, she tries reuniting with Matt Murdock, only to find out he is now with a blind woman named Milla Donovan, and that the Kingpin is still alive (despite Maya's attempts to kill him). Leaving Matt, Maya visits the Kingpin in prison, who tells her that he doesn't blame her for what she did, and that despite all that had happened, he still loves her like a daughter.[volume & issue needed]

Unsatisfied and still needing peace, Maya turns to the Chief, her father's old friend, noted for his wisdom. The Chief sends Maya on a Vision quest to calm her soul. On her quest, she meets and befriends Wolverine who helps her recover and passes on his knowledge of Japanese culture and Japanese organized crime. Soon enough, Echo makes peace with her past and is back doing performance art.[

Answer 2

What is an echo?

· Sound waves can be reflected off any reasonably flat surface like a cliff, high wall or mountain. When this surface is neither too near nor too far, a sound made by you hits the surface and comes back to you as an echo. The further the surface is from you, the weaker the echo and the longer it will take for the echo to return. The waves keep bouncing back and forth, getting weaker as they travel, until they lose energy and die out.

How are echoes useful to our society?

Mammals use echo locating

· Echoes are not only used by mammals like dolphins and bats, but they are also used by humans. Humans can also locate objects by using echoes. They make clicking sounds and start to listen to the faint returning echoes. Blind people were able to locate moving objects such as cars, trees and flagpoles.

Echocardiograms

· Echoes might seem useless, but in fact they are used to examine hearts for any problems. The machine that examines hearts is called echocardiogram. This machine uses echoes to measure heart chambers, valves and major blood vessels. This can be very helpful when there is a blood clot or tumors.
