REFLECTION OF SOUND IN AN OPEN PIPE

when a high pressure pulse of air travelling down an open pipe reaches the other end ,its momentum drags the air out into the open,where pressure falls rapidly to the atmospheric pressure.As a result the air following after it in the tube is pushed out.the low pressure at the end of the tube draws air from further up the tube.the air gets drawn towards the open end forcing the low pressure region to move upwards.as a result a pulse of high pressure air travelling down the tube turns into a pulse of low pressure air travelling up the tube.we say a pressure wave has been reflected at the open pipe end with a change in phase of 180.standing waves in an open pipe organ like the flute is a result of this phenomenon

kitchen gas lighter

one of the most important equipment in our house that is used on daily basis.so it is important to know about the discovery of this amazing product.the kitchen gas lighter was invented by CURIE.It works on the principle of piezoelectricity.A piezoelectric crystal is the heart of gas igniter.when a strong force is applied on it by means of a spring loaded hammer it produces an electric spark.certain dielectric materials have an internal crystalline structure which when subjected to mechanical stress produces an electric field .These materials are termed as piezoelectric crystals and this principle is termed as piezoelectricity.

piezoelectric spark producers are small devices used both in LPG and cigrette lighters.
