SSC Physics Note Chapter 7: Waves and Sound

SSC Physics Note Chapter 7: Waves and Sound. If we throw a stone into pond water, we see the wave. The wave carries energy from one place to another. The sound is a kind of wave. The sound energy can create the sensation of hearing. We can send information using sound. So the sound is closely related to our life. But sound pollution causes much harm to us. We shall discuss wave, sound, an echo of sound, velocity of sound, sound pollution etc. in this chapter.

The physics is one of the oldest academic disciplines, perhaps the oldest through the inclusion of astronomy. In the last two millennia, physics was a part of natural philosophy, chemistry, certain branches of mathematics and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique in its own right research programs. Physics intersects with many interdisciplinary areas of research, such as Biophysics and quantum chemistry, and physics limits are not rigidly defined. New ideas in physics often explain the fundamentals of other sciences mechanisms, to open new avenues of research in areas such as mathematics and philosophy.

teachingbd24.com is such a website where you will get all kinds of necessary information regarding educational notes, suggestions and question patterns of schools, colleges, and madrasas. Particularly, you will get here special notes of physics that will be immensely useful to both students and teachers. The builder of the website is Mr. Md. Shah Jamal who has been serving for 32 years as an Assistant Professor of Physics at BAF Shaheen College Dhaka. He expects that this website will meet up all the needs of Bengali version learners /students. He has requested concerned students and teachers to spread this website home and abroad.
