ASSIGNMENT --1
NUMERICALS
1.A person listening to a tone of 500 Hz sitting at a distance of 450m from the source of the sound.What is the time between successive compressions from the source?(Given speed of sound in air =330m/s)
2. An echo returned in 3s. What is the distance of the reflecting surface from the source?(Given Speed of sound is 342m/s)
3. A ship sends out ultrasound that returns from the sea bed and it is detected after 3.42s. If the speed of ultrasound through the sea water is 1531m/s, what is the distance of sea bed from the ship?
4. A person has a hearing range from 20 Hz to 20 KHz. What are the typical wavelengths of sound waves in air corresponding to these frequencies.(Given Speed of sound in air is 344m/s)
5. A submarine emits a SONAR pulse which returned from an underwater cliff in 1.02s. If the speed of sound in salt water is 1531m/s, how far away is the cliff?
