Sound waves are mechanical longitudinal waves and require a medium for their propagation.

Sound cannot propagate through vacuum. When it propagates, speed and wavelength changes but the frequency remain constant. It is of three types Infrasonic waves – (0 to 20 Hz) Audible waves – (20 to 20,000 Hz) Ultrasonic waves – (>20,000 Hz)

Properties of Sound Wave Reflection The bouncing back of sound when it strikes a hard surface, is called reflection of sound.The laws of reflection of light are also obeyed during reflection of sound.The working of megaphone, soundboards, and ear trumpets are based on the reflection of sound.The repetition of sound due to reflection of sound waves, is called an echo.

The minimum distance from a sound-reflecting surface to hear an echo is nearly 17 m.The persistence of hearing on the human ear is 1/10th of a second.
Soundproof rooms are made of two layers of walls having a vacuum between them.

The only way to learn MATHEMATICS is to do MATHEMATICS

Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations  sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The word trigonometry comes from the Greek words trigonon (“triangle”) and metron (“tomeasure”). The first use of the idea of ‘sine’ in the way we use it today was in the work Aryabhatiyam by Aryabhata, in A.D. 500. Aryabhata used the word ardha-jya for the half-chord, which was shortened to jya or jiva in due course. When the Aryabhatiyamwas translated into Arabic, the word jiva was retained as it is. The word jiva was translated into sinus, which means curve, when the Arabic version was translated into Latin. Soon the word sinus, also used as sine, became common in mathematical texts throughout Europe. An English Professor of…
