How to Draw Diagrams for Modes of vibrating Air column in a tube closed at One End – Smarter Techniques

“Harmonics in Closed Tube Explained with Diagram”


  An air column of length L is formed in a tube closed at one end. This air is made to vibrate by a tuning fork of frequency n. Then the air column will vibrate in different modes.

Fundamental or 1 st Harmonic  |    3 rd  Harmonics frequency.   |5 th  Harmonics frequency.

frequency.                                    |                                                      |

Let  V be the velocity of sound waves in air; then fundamental frequency n is given by

    Third harmonics frequency

Then the frequencies are 1st, 3rd, 5th... harmonics.

Thus, an air column in a tube closed at one end vibrates only with odd harmonics.

In my blog related to

 How to Draw Diagrams in Physics  by Smarter Techniques,

 I have discussed the general guideline to draw diagrams on an A4 sheet.

Do you want to know ' How to Draw Diagrams for Modes of vibrating Air column in a tube closed at One End?' using given guidelines.

Let us see from the following video for an actual smarter method of drawing a diagram.

Real concept of flow of Electrons in Conductor

Real concept of flow of Electrons in Conductor     Myself  Prof. KALI C. S. (M.Sc. M. Ed. D.C.S. ) having 45 years of Experience in Physics teaching. It is observed that there are misconceptions in the students regarding the flow of Electrons in the Conductor . Do you want to know the real secret of the   flow of Electrons in the Conductor ?  Then let us see the truth.                   Every conductor is made up of atoms. The atom consists of  Electron         (e-), Proton (  H +   ), Neutron (n 0  ). At the center of an atom, there is a nucleus containing protons and neutrons, making the nucleus positively charged. The electrons are revolving in different orbits around the nucleus. orbits round the nucleus.                      Fig A     Consider so...
