Bats search out prey and fly in dark night by emitting and detecting reflections of which type of Sound Waves?

Ultasonic Waves

The correct answer is option 4. Ultasonic Waves.

Bats search out prey and fly in the dark night by emitting and detecting reflections of ultrasound Waves.

Bats use a process called echolocation to navigate and locate prey in the dark. They emit high-frequency sound waves, typically in the ultrasonic range, which are above the range of human hearing. These sound waves travel through the air and bounce off objects in the environment. By detecting the reflections of these sound waves, bats can determine the location, distance, size, and texture of objects around them, including potential prey. Ultrasound waves are particularly well-suited for echolocation because they have short wavelengths, allowing for precise detection and localization of objects.
