Watson-Watt's Principle of Echo Location

Watson-Watt's Principle of Echo Location refers to the method of using sound waves to determine the location of objects. It involves emitting sound signals and analyzing the echoes that bounce back from surfaces. By measuring the time it takes for the echoes to return, one can calculate the distance to the object. This principle is used in various applications, including sonar technology for submarines and bats' navigation. Essentially, it demonstrates how sound can provide valuable information about the environment, enabling detection and ranging of objects even in complete darkness.
