Question

An animal that can hear ultrasonic sound waves.

Answer 1

Hint: Wave is the physical phenomenon that can be described as a disturbance that travels through a medium, transporting energy from one source to another without transferring matter.
The electromagnetic spectrum consists of 7 types of waves are:
Microwaves, infrared, optical, ultraviolet, x-ray, and gamma rays.

Complete answer:
In order to solve this question we need to know more about waves and sound waves.
Wave is the disturbance in a medium that helps in transport of energy from one location to another without transporting matter.

Waves come in two main categories:
1. Longitudinal waves
2. Transverse waves

> Longitudinal waves: These types of waves consist of alternating compressions and rarefactions in a medium.
For example: Sound waves, compression waves.

> Transverse waves: These types of waves are those in which the medium moves at the right angle to the direction of the wave.
For example: Water waves, light waves.
Properties of wave are:
- Amplitude
- Wavelength
- Period
- Frequency
- Speed

> Sound waves: sound waves are the type of longitudinal waves in which sound is propagated in a medium by following a path of compression and rarefaction.
Basic features of sound wave are:
1. Frequency
2. Amplitude
3. Spectrum
4. Duration
5. Location

Normal frequency is about 20 to 20,000 hertz.
Infrasonic sound waves are waves having frequency below 20 hertz.
Infrasonic waves are heard by animals like giraffes and elephants.
Ultrasonic sound waves are the waves having frequency above 20,000 hertz.
Animals such as bats, dos and dolphins can hear these high pitched sounds.

So, the correct answer to this question is dogs, bats and dolphins.

Note: The normal frequency of healthy young persons between 20 to 20,000 hertz.
The cochlea in the human ear is stimulated by a limited range of frequencies.
