Sound waves are produced by the vibration of material objects. A disturbance in the form of a longitudinal wave travels away from the vibrating source. High-pitched sounds are produced by sources vibrating at high frequency, while low-pitched sounds are produced by low-frequency sources Sound waves consist of traveling pulses of high-pressure zones, or compression, alternating with pulses of low-pressures zones, or rarefaction. Sound can travel through gases, liquids, and solid, but not through a vacuum.

it is about a chapter and learning this chapter is very important for class 8 and further standerds. it contains about sound,eye,ear, and its parts .all the best for your exams
Identify sound waves in nature and physics, the type of piezowaves accompanying them, the difference between sound waves audible to humans and between ultrasound and subsonic waves, how to theoretically calculate their speed when they pass through different physical media, calculate their frequency and wavelength, and the effect of temperatures and the density of different materials on these calculations
41. Sample Problem Chapter 12 Section 3 Harmonics 3. Calculate Substitute the values into the equation and solve: Case 1: The next two harmonics are the second and third:

43. Sample Problem Chapter 12 Section 3 Harmonics 4. Evaluate In a pipe open at both ends, the first possible wavelength is 2L ; in a pipe closed at one end, the first possible wavelength is 4 L . Because frequency and wavelength are inversely proportional, the fundamental frequency of the open pipe should be twice that of the closed pipe, that is, 70.4 = (2)(35.2).
