True or false? Ultrasound cannot be detected by the human ear but other animals like dogs and bats can hear it.FALSETRUE

Answer

The statement is True.

Explanation

Ultrasound refers to sound waves that have frequencies higher than the upper limit of human hearing, typically above 20 kHz. Humans can generally hear sounds in the frequency range of 20 Hz to 20 kHz. While humans cannot detect ultrasound, many animals, including dogs and bats, have the ability to hear these higher frequencies.

• Dogs: Can hear frequencies as high as 45 kHz.
• Bats: Are known for their echolocation abilities, which involve emitting and listening for high-frequency sounds that can exceed 100 kHz.

Thus, the assertion that ultrasound cannot be detected by the human ear but can be by other animals like dogs and bats is indeed true.
