sound is given by the formula The velocity of sound in iron was determined by two French investigators by striking one end of a long series of connected iron pipes with a hammer and measuring the time interval between the two sounds heard at the other end..

A narrow and long hollow tube of glass or a metal, open at both ends is taken. It is partially immersed vertically in a tall jar containing water. The length of the tube above the water level in the jar serves as an air column whose natural frequency depends on its length and the diameter..

If a coil carrying current is suspended by thin elastic long conductors, it will align itself as the compass needle, i.e., one end of the coil will point in the north direction and the other end will point towards the south. The polarity of the faces of the coil depends on the direction ..

Rule for Determining the Direction of Magnetic Field in a Coil Carrying Current - If a coil carrying current is suspended by thin elastic long conductors, it will align itself as the compass needle, i.e., one end of the coil will point in the north direction and the other end wi..

Reverberation - The persistence of audible sound even after the source has ceased emitting sound is called reverberation. If the reverberation of a sound pulse persists so long as to prolong the sound while several successive pulses are produced, th..

A sonometer, also called a monochord, was invented by Pythagoras (580-500 B.C.). It is a simple instrument used to verify the laws of stretched strings and to determine the frequency of a tuning fork. It consists of a long hollow rectangular wooden box (w) called the sound b..
