Both solar eclipses and lunar eclipses are shadows.
In a solar eclipse, the shadow of the Moon darkens a small spot on the Earth.
In a lunar eclipse, the shadow of the Earth hits the Moon. Because the Earth is much larger than the Moon, the Earth's shadow is much larger than the Moon's shadow, so in about half of the time, the Moon is completely shadowed. The small Moon shadow is rarely more than about 500 miles across on the Earth, so only a tiny part of the Earth experiences a solar eclipse.
Sonar is a sound phenominon, it requires a liquid (water, air, etc) to work.
Bats use sonar that they listen to and when it hits something and bounces back so they can find prey and avoid obstacles also bats are blind so the sonar is there only means of travel
Scientists Gary Numan, along with Bonnie Cylde.
It uses "sonar" technology where it can detect obstacles in front.
Bats have poor sight, but very good sonar: good enough to fly and catch insects.
The two different types of sonar are passive and active.
Eclipse
In 2012, solar eclipses are tentatively scheduled for May 20 and November 13, weather permitting.
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
STS1 is my old rate/rank, and one of the best in the Navy if you're on a fast-attack submarine. The STS stands for "Sonar Technician (Submarines) - the 1 is the rank, for First Class Petty Officer. Submarine and Surface Sonar Techs have different rate designations, as their school training pipeline is different. Surface Sonar designation is STG, for Sonar Technician(Guns).
An echo is a sound wave reflecting off an object. Sonar is a means of detecting object using sound waves, usually echoes.
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.
