basically same but sonar uses ultta sonic waves and echo uses sound in air
Sonar is a technology that uses sound waves to detect objects underwater by measuring the time taken for the sound waves to bounce back. An echo is the reflection of sound waves off a surface back to the source. Sonar is a system that uses echoes to create a map of the underwater environment.
The first sonar invention was called the "echo sounder" and was developed in 1913 by Lewis Fry Richardson. It was initially used to measure water depth by sending sound waves into the water and measuring the time it took for the echo to return.
When sonar waves hit the floor, they bounce back to the device that emitted them. The sound it produces is typically a quick and distinct echo, which can help determine the depth of the water or the distance to the floor.
Sonar is a system that uses sound waves to detect objects underwater, while ultrasound is a medical imaging technique that uses high-frequency sound waves to visualize internal organs and tissues in the body. Sonar is typically used in underwater navigation and communication, while ultrasound is used in medicine for diagnostic purposes.
Reverberation is the persistence of sound in an enclosed space due to multiple reflections, while an echo is a distinct repetition of sound caused by reflection off a surface.
Sonar location is in the water and echo location is in the air.
Echo is a program. '' is not a program. '' does not perform any action. Echo returns what you type. '' does not.

The types of echo sounders include single beam echo sounders, multi-beam echo sounders, and side-scan sonar. Single beam echo sounders are simpler and used for shallow water depths, while multi-beam echo sounders can cover a wider swath and provide more detailed bathymetric data. Side-scan sonar is used to produce images of the seafloor.

Echo is caused due to reflection of sound and it has major applications in SONAR, which is used by submarines or planes to detect other objects
rem is a comment that is only seen if you edit the batch echo actually is printed when the batch is running
echo cat will print out the word 'cat' on the command line. cat echo will attempt to list the contents of a file called 'echo'.
An echo is like a sonar because they both reflct the sound they cause. The sonar is useful to the navy army to find out where the lost ships are located, so basically they are navigating the exact location of ships and sumbarines. An echo as you can see can be most used when screaming in the gym or an enormous place with no one in there. I hope this helped you.
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.
Echo location, also called SONAR. This is just like the pinging you hear in a submarine movie
Print always returns a value of true, but echo doesn't. echo also has a short cut syntax meaning you can immediately follow the php tags by an equals sign and it will echo the result like in the example shown below: <?=$hello?>
