Explanation:
- Ultrasonic waves are the sound waves that have a frequency greater than 20,000 Hz.
- Bats and dolphins use ultrasonic waves for echolocation.
- Cows and dogs cannot hear ultrasonic waves because they do not have the ability to perceive high-frequency sounds.
- Cows and dogs have a limited range of hearing compared to bats and dolphins.
- The frequency range of cow's hearing is between 23 Hz to 35,000 Hz, and for dogs, it is between 67 Hz to 45,000 Hz.
- In contrast, the frequency range of hearing for bats is between 20 Hz to 120,000 Hz, and for dolphins, it is between 0.25 Hz to 150,000 Hz.
