WebApr 7, 2024 · One of the crucial chapters to study in this syllabus is sound. It is the 12th chapter in the subject that needs more attention from the students. They will learn how sound waves originate and how they propagate in a medium. This is the first time they will learn what an energy wave is and how it behaves in a medium. WebDistance travelled by sonar pulse = Speed of sound × Time taken = 1531 x 1.02 = 1561.62 m Distance of the cliff from the submarine = (Total distance travelled by sonar pulse) / 2 = 1561.62 / 2 = 780.81 m. Exercise Questions Page: 174 1. What is sound, and how is it produced? Solution: Sound is produced due to vibrations. lowest lot size share

WebThe table below lists the speed of sound in different media. The formula used to calculate the speed of sound is given as: c = d t Where, d is the distance traveled by sound t is the time taken to cover the distance. 1,074 Reflection Of Sound Reflection of sound is similar to the reflection of light. WebTo hear distinct echo sound, the time interval between original and reflected sound must be at least 0.1s. As sound persists in our brain for about 0.1s. Minimum distance for … WebThe explanation for incorrect options: Hertz is the unit of frequency and frequency is defined as the number of vibrations per second. Hence, the number of vibrations per second, which gives frequency in, s e c o n d - 1 = H e r t z. Hence, option (b) is correct. jane byrne blues brothers
