The pitch of sound depends on Frequency. Pitch refers to the perceived highness or lowness of a sound, which correlates directly with its frequency. Higher frequencies create higher pitches, while lower frequencies produce lower pitches.
The method used to ward off insects and harmful elements from homes is Ultrasonic wave. Ultrasonic devices emit high-frequency waves that are uncomfortable for pests like insects and rodents, encouraging them to leave the area. This technology is popular for ...
The phenomenon used to detect prey, predators, or obstacles is as Formation of pulses. Animals like bats use echolocation, emitting ultrasonic pulses and detecting their echoes to locate objects. This method allows for precise navigation and hunting in environments where ...
The first person to produce ultrasonic waves by whistling was Galton. Sir Francis Galton, a polymath and cousin of Charles Darwin, discovered ultrasonic waves in 1883 through his experiments with high-pitched whistles. His work laid the foundation for understanding and ...
Ultrasonic waves cannot be heard by humans. They have frequencies higher than 20,000 Hz, beyond the range of human hearing. While some animals can detect ultrasonic frequencies, humans cannot perceive these waves audibly without the aid of specialized equipment.
Ultrasonic waves have frequencies more than 20,000 Hz, beyond the upper limit of human hearing. They are used in various applications such as medical imaging, industrial cleaning, and sonar.
Infrasound waves have frequencies less than 20 Hz. They are below the threshold of human hearing, which ranges from 20 Hz to 20,000 Hz. Infrasound can be generated by natural events such as earthquakes and volcanic eruptions, as well as ...
When a bucket of water is rotated very fast in a vertical circle, the water does not fall from the bucket even from its highest position because centrifugal force is greater than the weight of water. Centrifugal force pushes the ...
When milk is churned vigorously, cream separates from it due to centrifugal force. Centrifugal force acts outward from the center of rotation, causing denser milk particles to move towards the outer edges of the container, while lighter cream particles move ...
