Question

Exholocation- is a form of sensory perception used by animals such as bats, toothed whales and dolphins. The animal emits a pluse of sound ( a longitudinal wave) which, after reflection from objects, returns and is detected by the animal. Echolocarion waves can have frequencies of about 100000 Hz. Estimate the wavelength of a sea animal's echolocation wave and if an obstacle is 100 m from the animal, how long after the animal emits a wave is its reflection detected​

Answer 1

Answer:

Echolocation is a form of sensory perception used by animals such a bats, toothed whales and porpoises. The animal emits a pulse sound (a longitudinal wave) wave is reflected from objects; the reflected pulse is detected by the animal. Echolocation waves emitted by whales have frequencies of about 200,000 Hz.
