16. What is the loudness of sound? What factors does it depend on? Solution: Loud sounds have high energy. Loudness directly depends on the amplitude of vibrations. It is proportional to the square of the amplitude of vibrations of sound. 17. Explain how bats use ultrasound to catch prey. Solution: Bats have the ability to produce high-pitched ultrasonic squeaks. These squeaks get reflected by objects, like prey, and return to their ears. This helps a bat to know how far its prey is. 18. How is ultrasound used for cleaning? Solution: Objects that need to be cleansed are put in a cleaning solution, and ultrasonic sound waves are passed through the solution. The high frequency of ultrasound waves helps in detaching the dirt from the objects. In this way, ultrasound is used for cleaning purposes. 19. Explain the working and application of a sonar. Solution: SONAR is an abbreviation for Sound Navigation and Ranging. It is an acoustic device used in measuring the direction, speed, and depth of underwater objects, such as shipwrecks and submarines, using ultrasound. Also, it is used to determine the depth of oceans and seas. A beam of ultrasonic sound is produced and travels through the seawater, which is transmitted by the transducer. When it reflects, an echo is produced, which is detected and recorded by the detector. It is then converted into electrical signals. The distance represented by ‘d’ of the under-water object is calculated from the time (represented as ‘t’) taken by the echo to return with speed (represented as ‘v’) is expressed as, 2d = v × t This method of measuring distance is also referred to as echo-ranging.
