The wavefront of the sound is spherical, so as distance increases, the intensity of the sound decreases proportionally to the square of the distance. There will be a point when the echo will not be strong enough to be detected above background sounds.

Why can't a sonic ranger detect objects less than 50 cm away?

A sonic ranger relies on sound waves to detect objects, and at distances less than 50 cm, the sound waves can bounce back too quickly for the sensor to accurately measure the distance. This limitation is due to the sensor's minimum sampling time and the time it takes for the sound waves to travel to and from the object.


How far can sonar detect?

The distance that sonar can detect objects underwater varies depending on factors like the power of the sonar system, water conditions, and the size of the object being detected. In general, sonar can detect objects up to several miles away when using higher power systems in optimal conditions.


What sonar has the disadvantage of alerting an adversary?

Active sonar emits sound waves to detect objects underwater and can be easily detected by an adversary, revealing the presence of the emitting vessel. This can potentially give away the vessel's position and compromise its stealth capabilities.


What is the point where two objects break away on a cladogram called?

The point where two objects break away on a cladogram is called a node. It represents a common ancestor from which the two objects diverged.


Why do objects that are farther look smaller?

Objects that are farther away appear smaller due to the phenomenon of perspective. As objects move away from the observer, the angle at which they are viewed decreases, making them appear smaller relative to closer objects. This is why distant objects seem to converge towards a vanishing point in the distance.

How did aristotles' inability to detect parallax lead him to propose a geocentric model of the solar system?

He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary. This erroneous assumption was because at the time he had no way of knowing that celestial objects were so far away that their parallax angles were too small to detect.He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary.
